Photocatalytic degradation of toxic pollutants, such as Volatile Organic Compounds (VOCs), involves the use of nanomaterials like fullerenes and Carbon Nanotubes (CNTs) to break down harmful substances under light exposure. The mechanism starts with the absorption of light energy by the photocatalyst, which generates electron-hole pairs. These electron-hole pairs are created when photons excite electrons in the nanomaterial to higher energy states, ______ __________ _______ ___ ______ _________ _________ _______.
