Abstract

Lanthanum-based perovskites have been gaining attention in recent years as cost-attractive and efficient catalysts for the oxygen evolution reaction (OER). Showing a simplified LaBO3 stoichiometry (B=transition metal cation), the structure and composition of the perovskites play key roles in their electrocatalytic performance. This paper aims to review the physicochemical concepts, structures, and recent advances on kinetic parameters for lanthanum-based perovskites for catalytic OER. First, advances on mechanisms and descriptors that govern general perovskites will be discussed in detail. Next, the current results for lanthanum cobaltite (LaCoO3), nickelate (LaNiO3), ferrite (LaFeO3), manganite (LaMnO3), and their derivations will be provided. Moreover, the existing results on less explored lanthanum perovskites for catalytic OER (LaCrO3, LaCuO3, LaVO3, and LaTiO3) will be also presented. The impacts of structural defects, orbital occupancy, materials morphology, and composition on the perovskite electrocatalytic performance will be assessed for each case. Finally, emerging trends for lanthanum-based perovskites will be provided. (AU)
