Introduction: A Delicate Collection of Advances in Solar‐to‐Chemical Conversions

Tremendous efforts have been made by worldwide researchers toward effective solar energy conversion and utilization. Compared with solar panels or solar cells that convert solar energy to electricity, photocatalytic process can store solar energy to chemical energies and then has attracted extensive attention. This book seizes this great timing to delicately collect the fundaments of solar-to-chemical technologies. Researchers, students, and broad readership would use this book to become experts from beginners. The researchers in the fields and the community may also find it useful for further advances to this exciting area. This book will cover the fundamentals in solar energy conversion to chemicals, either fuels or chemical products. Natural photosynthesis will be firstly presented to give a tutorial introduction while main attention will be focused on artificial processes for solar energy conversion and utilization. The chemical processes of solar energy conversion via homogeneous and/or heterogeneous photocatalysis will be described with the mechanistic insights. Reaction systems afford a variety of applications, for example, water splitting for hydrogen or oxygen evolution, photocatalytic CO2 reduction to fuels, and light-driven N2 fixation, etc. Emerging photocatalysis in upgrading or reforming fossil fuels will also be covered. Design and theoretical fundamentals of solar energy conversion to chemicals will be explained in detail based on semiconductor photocatalysis. Enormous research outcomes in the individual field are related to solar-to-chemical conversion, while this might be the first delicate collection detailing the fundamentals of each catalytic process, along with most challenging issues that hinder the processes move to an industrial scale. Therefore, it is believed that this book will be unique and can offer the readers a broad view of solar energy utilization based on chemical processes and their perspectives for future sustainability. This book includes 16 chapters and the brief information and highlights of each chapter are as follows:
