Exploring the Structure, Magnetic, Electronic, and Electrocatalytic Properties of Cation‐Disordered Double Perovskite SmFe 0.5 Cr 0.5 O ₃

Double Perovskites, where the B‐site is disordered, have been extensively studied because of their remarkable applications. We investigated the structural, magnetic, electronic, and catalytic responses of SmFe 0.5 Cr 0.5 O 3 (SFCO). We synthesized the compound successfully through the solid‐state method. The compound crystallizes in Orthorhombic structure with space group Pbnm as investigated using a powder X‐ray diffraction (PXRD) study. Magnetic investigation data (both M‐T and M‐H) confirm the existence of a weak ferromagnetic nature with T C at 290 K. The band gap of 2.21 eV, using an emission wavelength of 656 nm, indicates it as a visible light catalyst. The electrocatalytic hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) study reveals the potential application of SFCO in water splitting.
