Preface

This book provides guidance for researchers to better understand the properties of perovskite and the latest development of applications. It introduces the kinds of perovskite materials, crystal structures, physical and chemical properties, preparation

The authors who collaborated in this book have summarized present advances of perovskite oxides and halide perovskite in certain fields related to environment conservation and energy utilization, as well as their experience of perovskite-related research. The book contains nine chapters, organized in three sections that cover

The first section consists of an introductory chapter prepared by the editor for the purpose of presenting a brief background on perovskite materials. It describes that perovskite is a material with an ABX3 structure, which includes perovskite oxide and hybrid perovskite such as Ba2XOsO6 (X = Mg, Zn, Cd) and Cs2AgBiBr6. In this section, the crystal structures and morphologies of perovskite materials have been systematically introduced. Subsequently, we discussed the preparation methods of materials and devices. The synthesis techniques and application of perovskite oxides are discussed in detail in a separate chapter. Through the introduction of physical characteristics, it can provide help for the construction of high-performance devices. In view of the exotic properties of perovskite, the applications and development of perovskite materials in different fields including environment protection and energy utilization are illustrated.

The second section discusses environment conservation and energy utilization.

Specifically, this section highlights the progress of using perovskite materials for solar cells and focuses on elucidating a few challenges of these materials in various aspects. And then, different functionalities in perovskites are reviewed from abatement of pollutants to energy conversion and storage. Take a NOx removal as an example, this section overviews recent research on development of novel perovskite-based catalysts for NOx removal from diesel engine exhaust gases. This section provides precise concentrations on the over-all related of perovskite materials and explores the synthesis methods and morphologies. Finally, this section reveals the significant tasks and outlooks of perovskite photocatalytic applications.

The third section presents other applications including the quantum dot LED, resistive random-access memories, and half-metallic ferromagnetic and spintronic applications. The self-issue of perovskite materials and the solution to this problem are proposed in this section, which provides a strategy for constructing high performance devices.

The editor expresses his thanks to all the participants in this book for their valuable contributions and to Ms. Nina Kalinic Babic for her assistance in finalizing the work. Acknowledgment to the IntechOpen staff members responsible for the completion of
