Photocatalytic degradation of pollutants using ZnTiO3-Based Semiconductor

Abstract

Recently, removal of industrial organic wastes and harmful pollutants from water has been widely investigated for better environmental sustainability and protection. These hazardous pollutants not only lead to serious contamination but also problematic to human and aquatic life worldwide. Photocatalysis is an important chemical approach which has been established one of the most promising and "green" machinery to remediate the environmental related problem. Photocatalysis is a catalytic procedure, taking place on the surface of semiconducting material in the presence of illumination of light. Hence, seeking for a favorable catalysts with promising efficiency has been receiving a great deal of attention for enhanced photocatalytic activity. Various heterogeneous semiconductor photocatalysts, such as metal oxides, organic complexes and chalcogenides, have been used for photo degradation of pollutants. Recently, most dynamic oxides perovskite-type mixed metal oxides have been extensively examined and applied for environmental remediation because of their good physical and chemical properties with uncertainty of arrangement and structure. Among all, zinc titanate (ZnTiO3) is one of the most fascinating photocatalytic material and has been broadly explored for environmental protection. Therefore, this chapter compiles the recent advancement in perovskite (ZnTiO3) oxides as advanced photocatalysts for environmental remediation. © 2022 Scrivener Publishing LLC.
