This study explores the catalytic performance of TiO₂ thin films in hydrogen production through the hydrolysis of potassium borohydride. Experiments conducted under visible light, ultraviolet (UV) light, and darkness revealed that TiO₂ thin films achieved maximum hydrogen production efficiencies of 113% under UV light, 98% under visible light, and 90% in dark conditions. The hydrogen generation rates were calculated as 81,400 mL min⁻1 g⁻1 under UV light, 77,571 mL min⁻1 g⁻1 under visible light, and 54,330 mL min⁻1 g⁻1 in the dark. Critical parameters such as temperature, amount of catalyst, volume of HCl, and NaOH concentration were systematically varied and optimized to enhance efficiency. TiO₂ thin films deposited on glass coverslips using the magnetron sputtering technique were characterized via FE-SEM/EDS, XRD, and FTIR analyses, investigated their structural suitability and stability for catalytic applications. This work highlights the potential of TiO₂ thin films as efficient and durable catalysts for sustainable hydrogen production.
