Lanthanum cerate perovskites have been found to be the electrocatalysts for water splitting and other electrolysis under laboratory conditions. The lanthanum cerate perovskite is well known for its position in fuel cell technology as a highly active and compatible electrode material in solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs). A doped LaCe1-x MxO3 perovskite offers versatile solid state chemistry with defects balance and resulting electrochemistry poses the versatility for the important industrial process of water splitting. In this perspective, three series of LaCe1-x MxO3 (M=Cr3+, Fe3+, Al3+, x=0.02-0.10) nanopowders were envisioned and tested electrochemically by using cyclic voltammetry and impedance analysis for water splitting in KOH and methanol solution at ambient conditions. Hydrogen evolution reaction (HER) was multifold with all of the perovskite powders. There was an obvious correspondence between the electrocatalytic activity and the morphological, structural properties of the doped systems. The most proactive ceramic in each series was tested for the SOFC technology and average fuel cell performance was observed for a few samples under ambient FC conditions. Recent Publications: 1.
