摘要：As a free, clean, non-polluting, inexhaustible resource and a domestic energy source, solar energy has long been considered one of the most promising renewable energy sources in the world.\'1\' In view of solar energy utilization, the search for semiconductor photocatalysts that can harvest the wide spectrum of solar light, from ultraviolet (UV) to near-infrared (NIR) wavelength, and achieve efficient solar energy conversion remains one of the most challenging missions. TiO_2, as a most prominent and suitable material for solar energy harvesting, is widely studied in photocatalysis for the removal of inorganic and organic pollutants. However, TiO_2 possesses a wide band gap of 3.2 eV, allowing the material only to be activated by UV light, which accounts for only 5% of the incoming solar energy.
