Visible light active photocatalysts are a class of materials that can harness the energy of visible light (400-700 nm) to catalyze chemical reactions. Unlike traditional photocatalysts, which often require ultraviolet (UV) light, these advanced materials can operate under sunlight or indoor lighting, making them more practical for widespread use. Common examples include modified forms of titanium dioxide (TiO2), graphitic carbon nitride (g-C3N4), and doped zinc oxide (ZnO).
