Abstract :
Photocatalysis is a promising technology for environmental remediation and energy applications, where photocatalyst uses light energy to drive chemical reactions. The process involves excitation of electrons creating electron-hole pairs, that facilitate oxidation and reduction reactions. Key factors affecting photocatalytic performance include band gap energy, light intensity, catalyst loading, pH, reactant concentration etc. Photocatalysts are classified into types such as traditional metal oxides (e.g., TiO₂, ZnO), metal sulfides, graphene-based materials, plasmonic photocatalysts etc., each with unique properties and applications. The review emphasizes their use in degrading organic pollutants, removing heavy metals, water splitting etc., with a focus on advanced oxidation processes for enhanced pollutant degradation and wastewater treatment.
