Abstract

The present review describes the electrochemical aspects of electroless plating in four sections: (1) electrochemical polarization behaviours; (2) catalytic aspects of electroless plating; (3) mechanism of anodic oxidation of reductants; (4) methods for determination of the rate of electroless plating.

It is stressed that electrochemical polarization studies in an electroless plating bath is a powerful method for assessing the adaptability of the bath and for obtaining mechanistic information, although the anodic and cathodic reactions are more or less interdependent when they occur simultaneously. Catalytic aspects of electroless plating are discussed on the basis of the polarization curves for the anodic oxidation of reductants. The mechanism of anodic oxidation of reductants is discussed on the basis of a computer simulation of the current density-potential curve assuming several reaction schemes. Attention is focused especially on the occurrence of the volcano-shaped polarization curve. It is established that the polarization resistance (the slope of the current-potential curve at the electroless plating potential) is inversely proportional to the rate of electroless plating.

Roles of crystal defects in site-controlled preparation of metallic micro/nanostructures on silicon surface
2023, Sensors and Actuators A: Physical
Metallic micro/nanostructures are core components for building high-performance sensors and circuits. Nanoscratches on silicon (Si) surface have been demonstrated to induce the orientational deposition of metals; however, the effect of crystal defects on deposition remains unclear, which raises difficulties for preparing high-quality metallic micro/nanostructures. Herein, a site-controlled preparation strategy was proposed for obtaining high-grade Au micro/nanostructures on Si nanoscratches with the assistance of photoresist mask. The roles of Si oxide, amorphous Si (a-Si), and distorted Si were systematically investigated toward optimal preparation, and the involved mechanisms were further revealed based on surface conductivity detection and electron migration analysis. It was found that the scratch after removing top Si oxide and a-Si layers can facilitate the formation of compact Au structures. Further analysis indicated that Si oxide and a-Si can hinder electron migration in the scratched area, while distorted Si can promote electron migration which is more conducive to the redox reaction. The excellent practical applicability was demonstrated by detecting surface-enhanced Raman scattering spectra of malachite green molecules absorbed on the obtained Au line-structure arrays. Moreover, the prepared Au structures on Si can be mechanically transferred onto PDMS surface. This study opens a new road in the facile and cost-effective preparation of metallic micro/nanostructures, which are promising for extending microsensors applications.
Direct surface functionalization with metal and metal oxide nanostructures
2023, Encyclopedia of Nanomaterials
This article summarizes techniques for growing nanoscale metal and metal oxide crystals on substrate surfaces to impart them with functionality, focusing on chemical and physical vapor deposition, chemical bath deposition, electrodeposition, and electroless plating reactions which yield individual nano-objects or intensely nanostructured coatings instead of compact and smooth films. The topic is approached from a synthetic perspective which compares potential benefits and disadvantages of each method and emphasizes general concepts such as nucleation, growth, supersaturation, mass transport, adsorption, kinetic control, and symmetry breaking, which are relevant to all or multiple of the covered reactions, instead of confining the discussion to a specific material class, product morphology, target application, or deposition method. Particular attention is dedicated to studies covering fundamental aspects which pave the path towards improved control over the shape, size, composition, phase, and areal density of the deposited nanostructures, as well as harnessing such gains in synthetic precision to investigate structure-property relationships and to create high-performing materials. It is exemplified how the employed deposition techniques – which often are mutually compatible and modular in nature – can be combined to rationally design hierarchical, hybrid and compositionally complex nano-architectures.
Effects of the method of active site characterization for determining structure-sensitivity in Ag-catalyzed ethylene epoxidation
2022, Journal of Catalysis
Catalysts have been prepared on a low surface area α-Al₂O₃ support used commercially for previous generation olefin epoxidation catalysts. Prescreening of the low surface area alumina (0.73 m²/g) indicated the absence of acid catalyzed isomerization of EO at an evaluation temperature of 210 °C. A 0.1 wt% Ag base material synthesized by incipient wetness impregnation of AgNO₃ was used as a base material for electroless deposition (ED) of additional Ag to increase particle sizes by controlled reduction of Ag⁺ directly onto the preexisting Ag surface to form weight loadings between 0.3 and 5.0 wt% metal. A 12 wt% Ag/α-Al₂O₃ using Ag₂C₂O₄ as the Ag precursor was also prepared to compare performance of the ED samples with a catalyst more typical of industrial formulations. Characterization by SEM, STEM, and hydrogen titration of oxygen precovered Ag characterized before and after catalytic evaluation indicated that microscopy is required to accurately represent distributions of Ag particle sizes, but H₂ titration of O-precovered Ag gives the best representation of active sites since it directly counts the number of Ag surface sites. Larger particles >100 nm are resistant to both Ag sintering and carbon foulant; TOF values were relatively insensitive to particle size with only a 2.2 × difference between the best and worst performing samples. Selectivity, which is not a function of TOF, shows the most significant structure sensitivity effect where particle sizes follow the trend 67 nm ≈ 92 nm (58% EO) < 157 nm (67% EO) < 211–542 nm (73% EO). The lower EO selectivities were also correlated with increased fouling for the smaller Ag sizes, suggesting that more strongly bound EO precursor(s) leads to combustion and CO₂/H₂O formation.
A review on multifunctional aerogel fibers: processing, fabrication, functionalization, and applications
2022, Materials Today Chemistry
Aerogels have been frequently reported in three-dimensional (3D) monolith bulk, granule, and two-dimensional (2D) thin-film geometries. However, their commercialization has been widely restricted due to the lack of flexibility, extensibility, and fragile network structures. Recently, a new class of aerogels, i.e. aerogel fibers has emerged. When conventional aerogels are transformed into fibers (sub-micron or nanofibers), their performance may enhance remarkably. Therefore, such aerogel fibers can exhibit improved mechanical performance, favorable flexibility, higher tensile strength, and enhanced extensibility. This will make them a suitable candidate for applications that require high mechanical flexibility and to be stretchable. In conjunction with the superior thermal insulation performance of aerogels, aerogel fibers can be extensively used in other commercial sectors where load-bearing is crucial. In this short review, we intend to assess the current technologies for the production of aerogels in fiber geometry, called “aerogel fiber.” Materials used for this purpose, along with the post-processing and functionalization methods, are also evaluated. Their recent breakthroughs in emerging applications in a variety of engineering fields are covered. A discussion of current challenges, limitations, and the urgent need for the development of new technologies for the continuous production of aerogel fibers is provided. A road map pointing to a future direction in aerogel fiber field will be discussed.
Autogenous growth of highly active bifunctional Ni–Fe<inf>2</inf>B nanosheet arrays toward efficient overall water splitting
2022, International Journal of Hydrogen Energy
Developing an effective and low-cost bifunctional electrocatalyst for both OER and HER to achieve overall water splitting is remaining a challenge to meet the needs of sustainable development. Herein, an electroless plating method was employed to autogenous growth of ultrathin Ni–Fe₂B nanosheet arrays on nickel foam (NF), in which the whole liquid phase reduction reaction took no more than 20 min and did not require any other treatments such as calcination. In 1.0 M KOH electrolyte, the resulted Ni–Fe₂B ultrathin nanosheet displayed a low overpotential of 250 mV for OER and 115 mV for HER to deliver a current density of 10 mA cm⁻², and both OER and HER activities remained stable after 26 h stability testing. Further, the couple electrodes composed of Ni–Fe₂B could afford a current density of 10 mA cm⁻² towards overall water splitting at a cell voltage of 1.64 V in 1.0 M KOH and along with excellent stability for 26 h. The outstanding electrocatalytic activities can be attributed to the synergistic effect of electron-coupling across Ni and Fe atoms and active sites exposed by large surface area. The effective combination of low cost and high electrocatalytic activity brings about a promising prospect for Ni–Fe₂B nanosheet arrays in the field of overall water splitting.

2021, Surface and Coatings Technology
With an advanced understanding of cathode materials in Li-ion batteries (LiBs) and supercapacitors, it has been observed that the surface structures of cathodes play an important role in these devices and significantly affects the whole system's performance e.g. maintain the structural stability and material's conductivity. Various approaches are being applied to enhance the electrochemical performances of batteries and supercapacitors e.g. doping of transition metal ions, synthesis of composite materials, synthesis of nanomaterials, and surface modification of materials. Among these techniques, surface modification of the electrode materials is widely used because of ease of synthesis and cost effectiveness. In the present article, the recent advancements in surface modifications of the energy storage electrode materials and their electrochemical performances are summarized. First, coating strategies and their effects on cathode are discussed and then the current research progress focusing on the surface coating materials are covered. At last, the challenges faced are discussed to improve the performances of cathode materials. In this study, we are presenting that the selection of coating materials and technologies plays a vital role in the advancement of cathode materials.
