Perovskite-type lanthanum ferrite based photocatalysts: Preparation, properties, and applications

This critical review summarizes the basic principles of photocatalysis, trends, challenges, and prospects perovskite type LaFeO 3 based photocatalysts in photocatalysis. Clean energy a sustainable environment are grand challenges that world is facing which can be addressed by converting solar into transportable storable fuels (chemical fuel). The main scientific technological for efficient conversion, storage, environmental applications stability, durability, performance low-cost functional materials. Among different nanomaterials, has been extensively investigated as photocatalyst due to its abundance, high compositional structural flexibility, electrocatalytic activity, sunlight absorption, tunable band gap edges. Hence, it urgent write comprehensive highlight trend, field photocatalytic conversion purification. history Further, reviews detail , applications, shortcomings, activity enhancement strategies including design nanostructures, elemental doping, heterojunctions construction such Type-I, Type-II, Z-Type, uncommon heterojunctions. Besides, optical electronic properties, charge carriers separation, electron transport phenomenon alignment gaps -based heterostructures comprehensively discussed.
