Photocatalytic water treatment by perovskite materials: Review

Researchers worldwide are actively exploring the enhancement and utilization of visible-light energy for environmental remediation and the degradation of organic and other pollutants. Over the past 20 years, significant efforts have been dedicated to developing safe and cost-effective photo catalysts with well-structured configurations that exhibit stability under light exposure. Among the numerous reported photocatalysts, oxides of ternary metals doped with non-metals and metals have garnered attention. Notably, perovskite materials have gained popularity as photocatalysts based on semiconductors because of their adaptability in synthesis methods and simplicity in production. Perovskite materials exhibit unique properties that render them highly appealing for photocatalytic applications, including their remarkable charge carrier mobility, adjustable bandgap, and outstanding light absorption capabilities. These inherent qualities make perovskites suitable for a wide range of photocatalytic applications. The review emphasizes on the current progress of similar perovskite materials and the systems they are connected to emphasizing diverse synthesis strategies, morphological aspects of perovskite materials, and prospective research directions for perovskite-based photocatalytic applications.
