Tackling Challenges in Perovskite‐Type Metal Oxide Photocatalysts

Solar energy‐driven photocatalysis is one of the most promising ways of environmental remediation and clean energy production. Over the past few decades, great efforts have been devoted to develop nontoxic, low‐cost, efficient, and stable photocatalysts. Among them, perovskite‐type metal oxides and their derivatives (layered perovskite‐type metal oxides) have attracted wide attention because of their unique structure and optical properties. This review summarizes the progress and application of perovskite‐type metal oxide photocatalysts, focusing on discussing the effects of different material modification methods on the structure and photocatalytic properties. The possible design strategies of perovskite‐type metal oxide photocatalysts in the future are put forward, which are of great significance to the development of photocatalytic materials.
