The class of inorganic solids, metal oxides composed of low-cost and earth-abundant elements have been an important family of functional materials. The transition metal oxides (TMOs) are special because they can form different cationic oxidation states, shows compositional and structural diversity, which offers electronic and crystal structure flexibility with various desirable physical/chemical properties. TMOs-based materials have received considerable interest for various applications. But TMOs have low intrinsic electrical conductivity and catalytic activity for energy related application. Many atomic level modification strategies have been proposed to address the intrinsic electrical conductivity of TMOs such as doping, oxygen-vacancy engineering, phase-structure engineering, strain engineering, morphology engineering, crystallinity engineering, valence regulation, composition optimization and hybridization; this may convert TMOs catalysts from semi-conductors into metallic-like conductors, resulting in increased catalytic activity. In my talk, I am going to focus on few modification strategies of TMOs for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) applications.
