Photocatalytic activity of attapulgite–TiO2–Ag3PO4 ternary nanocomposite for degradation of Rhodamine B under simulated solar irradiation

Abstract An excellent ternary composite photocatalyst consisting of silver orthophosphate (Ag3PO4), attapulgite (ATP), and TiO2 was synthesized, in which heterojunction was formed between dissimilar semiconductors to promote the separation of photo-generated charges. The ATP/TiO2/Ag3PO4 composite wa...
