Comprehensive Review on Synthesis of Abox Material and its Catalytic Applications

Abstract

Perovskites are materials with crystal structures comparable to perovskite (mineral). The backbone of perovskite is calcium titanium oxide (CaTiO3). Perovskite oxides with the general formula ABOx are highly important. In the general formula of perovskite ABX3, A & B are cations, where X is an anion that binds with two cations. Perovskites have proven their versatility in catalysis, photovoltaics, solar cells, electrode conducting material, etc. Due to their unique structural properties and applications, they are compatible with elements having metallic approximately 90% of the periodic table.This review discusses the synthesis and catalytic application of perovskite oxides. There are five sections to this review: (a) a brief description of perovskite oxides, (b) the synthesis of perovskite oxides with various properties, (c) general characterization, (d) catalytic applications, and (e) conclusions and future perspectives.

Composition‐Dependent NiS‐Enriched FeNi2S4/ZnCr2O4 Catalyst for Electrochemical Oxygen Evolution Reaction

“…[7][8] The basic reactions are the same, even if these devices are constructed differently. [9] The hydrogen evolution reaction (HER) at the cathode electrode and the oxygen evolution reaction (OER) at the anode is involved in a water-splitting device, [10][11][12][13][14] while metal dissolution and deposition take place at the negative (metal) electrode and the oxygen reduction reaction (ORR) and OER at the positive electrodes are involved in a rechargeable metal-air battery. [15] Since OER is the most efficient of the two technologies and involves the formation of oxygenoxygen bonds and four proton-coupled electron transfer processes, it is kinetically slow compared to the other halfreactions.…”
