<正>When exposed to light,titanium dioxide(titania,TiO2)can act as a powerful catalyst for degrading a variety of organic compounds.Anatase—one of the polymorphs of TiO2—has a band gap of 3.2 e V;exposing it to ultraviolet light causes the formation of electron-hole pairs,which,in the presence of water,can generate hydroxyl radicals—strong oxidizing agents.The photocatalytic behavior of titania has enabled
