Abstract
Perovskite-type catalysts have been prominent oxide catalysts for many years due to attributes such as flexibility in choosing cations, significant thermal stability, and the unique nature of lattice oxygen. Nearly 90% metallic elements of the Periodic Table can be stabilized in perovskite’s crystalline framework [1]. Moreover, by following the Goldschmidt rule [2], the A- and/or B-site elements can be partially substituted, making perovskites extremely flexible in catalyst design. One successful example is the commercialization of noble metal-incorporated perovskites (e.g., LaFe0.57Co0.38Pd0.05O3) for automotive emission control used by Daihatsu Motor Co. Ltd. [3]. Thus, growing interest in, and application of perovskites in the fields of material sciences, heterogeneous catalysis, and energy storage have prompted this Special Issue on perovskite catalysts.

Catalysts 2014, 4 ethylenediaminetetraacetic acid-citric acid method to prepare monophasic crystalline LaNi0.3Co0.7O3−δ and SrFe0.2Co0.8O3−δ, and investigated their performance in CO oxidation
During oxygen evolution in electro-catalytic water splitting, the Mn ions can be reduced to a bivalent state as oxygen vacancies are formed on the surface of perovskite
We appreciate the efforts taken by the aforementioned groups
