GdFeO₃ is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Gd³⁺ is bonded in a 8-coordinate geometry to eight O²⁻ atoms. There are a spread of Gd-O bond distances ranging from 2.27-2.70 Å. Fe³⁺ is bonded to six O²⁻ atoms to form corner-sharing FeO₆ octahedra. The corner-sharing octahedral tilt angles range from 34-35°. There are a ...

In electrochemical (EC) water splitting, water gets splits into H 2 and O 2 on applying sufficient electrical energy. H 2 and O 2 generation are two- and four-electron processes, respectively, but oxygen evolution reaction (OER) is what controls the efficiency of an electrocatalyst in water splitting. This is due to slow and sluggish kinetics of four-electron …
