Über dieses Buch

This brief provides a comprehensive overview of contemporary research and materials technologies utilizing oriented-attachment nanocrystals (OA NCs) for the energy conversion devices. Starting with a historical introduction, the book presents basic theory with an emphasis on thermodynamic and kinetic models of the oriented-attachment nanocrystals growth. Further chapters review recent advances in the synthesis, characterization, and application of the oriented-attachment nanocrystals in fuel cells, batteries, supercapacitors, solar cells and photocatalysis. This book will appeal to researchers and scholars from a variety of disciplines including electrochemistry, materials science, chemical engineering, physics and mechanical engineering.

Chapter 1. Introduction to Oriented-Attachment Growth Mechanism
Abstract
Inorganic crystal materials have been extensively used in various fields in our life, including telecommunication, medical treatment, and aerospace, due to their fascinating optical, electrical, mechanical, and magnetic properties.

Chapter 2. Oriented-Attachment Nanocrystals in Fuel Cells
Abstract
Fuel cells are devices that convert chemical energy to electricity through reaction of fuels with oxygen. Different from batteries that are defined as storage energy devices, fuel cells can continuously generate electricity as long as fuels are supplied sufficiently [1].

Chapter 3. Oriented-Attachment Nanocrystals in Lithium Ion Batteries
Abstract
The world has entered an era with an increasing demand for new energy, including wind, tide, solar, and geothermal energy, due to the prompt reduction of fossil-based energy. But these new energies are subject to the restrictions of space and time. To address these issues, renewable energy storage devices have been developed, such as the lithium ion batteries (LIBs).

Chapter 4. Oriented-Attachment Nanocrystals in Supercapacitors
Abstract
Supercapacitors are the energy storage devices with high power density (1–10 kW kg−1), long lifetime (500,000–1,000,000 cycles), fast charging (with seconds), a wide range of operation temperatures (−40 to 70 °C), and high safety.

Chapter 5. Oriented-Attachment Nanocrystals in Solar Cells
Abstract
Solar cells convert solar energy into electricity directly. The first-generation solar cells, which are silicon-based photovoltaic devices are efficient but costly. Although second-generation solar cells are cost-effective, the conversion efficiency is not desirable. Now, people are focusing on the third-generation solar cells with low cost, highly efficiency, and non-toxicity.

Chapter 6. Oriented-Attachment Nanocrystals in Photocatalysis
Abstract
Environment pollution and energy crisis are serious challenges in the world. Photocatalysis is a process of harvesting the energy from solar light and then transferring the energy to available chemical species.
Weidong He, Kechun Wen, Yinghua Niu
Chapter 7. Conclusions and Trajectories for the Future
Abstract
As a new crystal growth mechanism, OA growth has developed into a fundamental growth mechanism in the general materials field. Compared with the traditional OR growth mechanism, OA presents a unique growth pathway and characteristics.
