Significant Role of Perovskite Materials for Degradation of Organic Pollutants

Abstract

The advancement and the use of visible energy in ecological reparation and photodegradation of organic pollutants are being extensively investigated worldwide. Through the last two decades, great exertions have been dedicated to emerging innocuous, economical, well-organized and photostable photocatalysts for ecofriendly reparation. So far, many photocatalysts mostly based on ternary metal oxides and doped with nonmetals and metals with various systems and structures have been described. Among them, perovskite materials and their analogs (layertype perovskites) include an emerged as semiconductor-based photocatalysts due to their flexibility and simple synthesis processes. This book chapter precisely concentrates on the overall of related perovskite materials and their associated systems; precisely on the current progress of perovskites that acts as photocatalysts and ecofriendly reparation; explores the synthesis methods and morphologies of perovskite materials; and reveals the significant tasks and outlooks on the investigation of perovskite photocatalytic applications.

Efficient Photocatalytic Degradation of RhB by Constructing Sn3O4 Nanoflakes on Sulfur-Doped NaTaO3 Nanocubes

“…For this reason, there has been an upsurge in research on a variety of photocatalysts. Among these, ABO 3 perovskite-type oxides have been widely studied, due to their high performance in photocatalytic reactions, such as with overall water splitting and the photodegradation of organic pollutants, which provide a potential approach to solve our urgent energy and environmental problems [8,9]. Sodium tantalite (NaTaO 3 ) is a prominent ABO 3 perovskite-like oxide with a high performance in photocatalytic reactions, including abundance, photochemical stability, photodegradation of organic pollutants, water splitting, and low environmental impact, which attracts a lot of attention for its favorable layered structure and distinctive separation effectiveness in charge separation [10][11][12][13][14][15][16][17][18][19][20].…”
