Preface

We are living in a rapidly developing world, especially advance in the fields of science and technology. Our science research and technology development are approaching into the new era. In the past decades, we produced new chemicals by reactions via heating at high temperatures. Nowadays, we can realize our reactions via light or electrics, which is considered as green means. The change from conversional means to green means will be advocated to protect our environment.

CO2 is room‐temperature gas, which can increase our air temperature with the increase of concentration of CO2 emission. Therefore, it is urgent to control its emission. In addition, the conversion and storage of CO2 are also widely paid attention to. As chemical workers, we focus more attention to how CO2 is converted into other useful chemicals, especially by green catalytic processes. Ammonia synthesis by electrocatalysis means is highly efficient and energy‐saving process, compared with conversional reaction, which can provide us the fertilizer.

O2‐involved reactions (O2 reduction reaction, ORR and O2 evolution reaction, OER) are crucial for metal–air batteries and fuel cells, which are considered as promising battery technologies. However, highly efficient catalysts for ORR and OER are desired to be explored. Another reaction about H2 product is also believed to be very important since H2 is the cleanest fuel, which can be used in fuel cells to produce to water.

We are obligated to study the green catalytic processes on above useful reactions including photocatalytic, photoelectrocatalytic, and electrocatalytic reactions. The main targets for studying these reactions should be included, i.e. the understanding of reaction mechanisms, the design and preparation of catalysts, and the development of characterization technologies. To facilitate the development of this field, we write this book, and hope potential readers from all levels get insights from these reactions. Finally, we hope that this book can inspire more people to pay attention to these technologies and can be devoted to the development of green catalytic reaction processes.
