Photocatalysis uses light-activated catalysts (e.g., TiO2) to drive chemical reactions, such as water splitting to generate hydrogen or degradation of pollutants. The catalyst absorbs photons, creating electron–hole pairs that initiate redox reactions. Photocatalysis holds promise for green energy production and environmental remediation, though improvements in efficiency and visible-light activation are ongoing research areas.
