Modifying TiO2 Nanoparticles by Atomic Layer Deposition for Enhanced Photocatalytic Water Purification

Photocatalysts, contrary to conventional catalysts, utilize light to drive a reaction. By absorption of photons, electrons are excited and reach higher states to initiate a redox reaction. This principle can be broadly used to produce chemicals such as hydrogen via the reduction of water or transform carbon dioxide into solar fuels, i.e.,...
