摘要：In this work, a novel photocatalyst Ag10Si4O13was synthesized through a facile solid state reaction. The as prepared Ag10Si4O13was characterized by XRD, SEM, TEM, UV–vis and XPS. The photocatalytic capability of Ag10Si4O13was estimated through photo-degradation of MB solution and photocatalytic oxygen generation under visible light irradiation. TOC changes of MB solution before and after photocatalytic experiment identified the mineralization of MB molecules. During photocatalytic oxygen generation reaction, Co3O4was used as cocatalyst to boost oxygen evolution. Compared with pure Ag10Si4O13, 4% Co3O4/Ag10Si4O13showed higher efficiency in oxygen evolution. Radical-trapping experiments and results show that holes generated by Ag10Si4O13are main active ingredient-oxidizing organic pollution under light irradiation.
