Perovskite oxides are a class of materials defined by their unique crystal structure. Such family of compounds follows a general formula ABO3, where A is a rather large cation (like Sr or La) while B is a smaller transition metal cation, such as those of the first row of the periodic table. Nowadays, perovskite oxides play a critical role in advancing technology and scientific research due to their remarkable versatility and tunable properties. In particular, the main thread of this presentation is associated to perovskite oxides, aiming at providing a broad overview on a general preparation method of multiple perovskite oxides, allowing to highlight specific examples in the domains of electrocatalysis, photoelectrocatalysis and photochemistry. Typical examples to be covered are (i) the use of Rh:SrTiO3 for the visible-light-driven production of hydrogen, (ii) the activity of La0.85Fe0.9Cu0.05Pd0.05O3 for methanol electrooxidation and (iii) the self-assembly of La0.85Mn0.9Cu0.1O3 within complex polymeric networks, thus permitting to emulate certain higher-order behaviors observed in living systems, taking advantage of the photocatalytic activity of the perovskite. In conclusion, this work will convey a general vision on the emerging field associated to perovskite oxides, and how they are having a huge impact in the contemporaneous research tied to perovskite oxides, highlighting the significant influence such materials exert on contemporary research.
