Perovskite inorganic perovskite-type oxides are intriguing nanomaterials with numerous uses in electrochemical sensing, fuel cells, and catalysis. Because they are catalytic when employed as electrode modifiers, perovskites made at the nanoscale have recently attracted a lot of attention. These oxides have stronger catalytic activity than many compounds made of transition metals and even some oxides of precious metals. They display desirable physical and chemical properties like electronic conductivity, electrical activity, oxygen content variations, mobility of oxide ions through the crystal lattice, thermal and chemical stability, and super-magnetic, photocatalytic, thermoelectric, and dielectric properties. In oxygen reduction and hydrogen evolution events, nano-perovskites have been used as catalysts because they have strong electrocatalytic activity, low activation energy, and strong electron transfer kinetics. Additionally, some perovskites provide good prospects for the production of efficient anodic catalysts with high catalytic performance for direct fuel cells. They can improve the performance of the catalytic process in terms of selectivity, sensitivity, exceptional long-term stability, good repeatability, and interference-fighting capacity.
