My research interests encompass the rational design and synthesis of nanomaterials, with particular emphasis on controlling morphology, surface chemistry, and electronic structure to achieve enhanced functional performance. Various metal oxides, chalcogenides, vanadates, molybdates, and carbon-based nanostructures are engineered to tailor physicochemical properties for targeted energy and environmental applications. A major focus of my work is photocatalysis, where light-driven processes are explored for sustainable chemical transformations. Efforts are directed toward understanding charge generation, separation, and transfer dynamics under UV–visible and solar irradiation to improve catalytic efficiency and reaction kinetics. Special attention is given to heterojunction photocatalysts, including type-II, Z-scheme, and S-scheme systems, to suppress charge recombination and promote directional charge migration. Interfacial band alignment and synergistic interactions between coupled semiconductors are systematically optimized for superior photocatalytic performance. In the area of hydrogen production, my research addresses both photocatalytic and electrochemical water splitting, with a focus on efficient hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) catalysts. These studies aim to develop cost-effective, stable materials for green hydrogen generation while simultaneously advancing environmental remediation, particularly the photocatalytic and electrochemical treatment of wastewater contaminated with organic pollutants.
