Lattice distortion-driven band gap engineering and enhanced electrocatalytic activity of Mn-substituted nanostructured SrTiO materials: A comprehensive investigation.

The lattice distortion and electrocatalytic activity are investigated by the mono-substituent of Mn with different concentrations to generate localized states in the electronic structure of SrTiO. The sol-gel approach has been employed to fabricate SrTiO and SrTiMnO nanostructures (NSs). The structural analysis indicates Mn incorporation into Ti sites of SrTiO, which shifts the lattice towards a higher diffraction angle with a single-phase cubic structure.
