Tackling Challenges in Perovskite‐Type Metal Oxide Photocatalysts

Abstract

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.

“…8(g) and (h)). 171,172 The photocatalytic activity of Cs 3 Sb 2 Br 9 perovskite for CO 2 reduction reaction has been explored recently. 124 Unlike the commonly used solvent ethyl and C–O bond formations via aryl esterifications.…”

Engineered magnetic oxides nanoparticles as efficient sorbents for wastewater remediation: a review

“…Fortunately, in double perovskite oxides, the facility to flexibly change the ions of the A or B sites makes it relaxed to modify the optical properties to fascinate the photocatalytic properties. Moreover, the little interaction between the double perovskites facilitates the introduction of hetero-cations, increasing the light absorption range and advancing photocatalytic activity (Chen et al 2016a;Ma et al 2021). M. Bhuyan and his colleagues focused on the optical properties of Gd 2 FeCrO 6 nanoparticles as a double perovskite.…”

Lead-Free Halide Perovskites for Photocatalysis via High-Throughput Exploration

“…Nonetheless, the primary drawback associated with the current photocatalysts lies in their wide band gap, deep trap states, rapid recombination of charge carriers, surface reconstruction, and nonreproducibility. , Furthermore, the synthesis conditions for these oxide-based photocatalysts are exceptionally harsh and time-consuming, necessitating high temperatures and pressures. − Hence, the synthesis process is energy-intensive and cost-ineffective. Consequently, due to these aforementioned limitations, the practical commercialization of these existing photocatalysts is unfeasible owing to their inefficient catalytic performances.…”
