A Brief Review on Key Role of Perovskite Oxides as Catalyst

Abstract The research work conducted mainly on the reduction reaction of NO x , the oxidation reaction of CO, and hydrocarbons, electro‐catalysis of oxygen in alkaline medium, and photocatalytic water splitting has proved excellent catalytic behavior of perovskite oxides. [16–23] Although only a few reports published usages of the perovskite oxides as catalysts for the organic transformation such as catalytic hydrogenation, Ullmann, Sonogashira reactions, and Suzuki couplings. [24–26] Yoon et al. have prepared K 2 CO 3 based LaMn 1‐x Cu x O 3 perovskite oxide as a potential catalyst and discussed their mechanistic aspects in various reactions occurring at room temperature. [27] Recently, Wu and Ajayan group has demonstrated the relationship between stoichiometry and activity of pure and B‐site substituted layered perovskite oxide in the decomposition reaction of isopropanol by considering Sr 2 Sn 1‐x Ru x O 4 (0≤x≤1) as catalyst. [28] In this scenario, present work aims to summarize the contribution of perovskite oxides as catalyst in numerous organic syntheses and catalysis, photocatalysis, and electrocatalysis reactions.
