About this book

This book explores the formation of colloidal gold–copper (AuCu) alloy nanoparticles and evaluate their application in heterogeneous catalysis. Metal alloys are extremely versatile materials that have been used since the Antiquity to improve the properties of commonly used metals, therefore the understanding of their properties has fostered the applications in areas such as photonics, sensors, clinical diagnostics, and especially in heterogeneous catalysis, which allows catalyst active sites to be modulated.

In this book, readers will appreciate the fundamental aspects involved in the synthesis of AuCu nanoalloys, including real-time information about their atomic organization, electronic properties, as well a deeper understand about the behavior of AuCu supported nanoalloys under real catalytic conditions, providing interesting insights about the effect of the support on the nanoalloy stability.

The results presented here open new horizons for using metal alloys in catalysis and also other areas where the metal–support interface may play a crucial role.

Chapter 2. Synthesis of Gold-Copper Nanoparticles by Colloidal Method Varying the Compositions as a Function of the Synthesis Final Temperature
Abstract
Advances in the synthesis of nanomaterials have contributed to the development of strategic areas, especially on the demand for new materials and technologies for energy production. In this way, it becomes indispensable deeper studies about the steps involved in the formation process of nanoparticles. Therefore is presented in this Chapter a systematic study about the nucleation and growth process the AuCu colloidal nanoparticles using the one-pot method. In situ XAFS studies demonstrate the process of digestion ripening-like process in the formation of the alloy, leading to a complete overview of the synthesis and pointing out key steps that lead to a fine control of size and composition of colloidal alloy.

Chapter 3. AuCu Nanoparticles Applied on Heterogeneous Catalysis: Studies About the Stability of Nanoparticles Under Redox Pre-treatments and Application in CO Oxidation Reaction
Abstract
Catalysis is an important area of great scientific and economic interest and in order to better understand the processes involved became essential the use of model catalysts with well defined properties. This Chapter presents AuCu nanoparticles with well defined size and composition supported and applied in the CO oxidation reaction. The results have proved the fundamental effect of the support as a driving force that leads to the formation of different types of metal-oxide interface, aspects that may be extremely relevant for catalysis and other areas where a well-defined interface is required.
