Combinatorial Discovery of Visible-Light Driven Photocatalysts Based on the ABO3-type (A= Y, La, Nd, Sm, Eu, Gd, Dy, Yb, B = Al and In) Binary Oxides

A combinatorial approach was used to systematically investigate the photocatalytic activities of different kinds of ABO(3)-type oxides (A = Y, La, Nd, Sm, Eu, Gd, Dy, Yb; B = Al, In). Two novel photocatalysts, cubic YInO(3) and perovskite YAlO(3), were identified rapidly. Scale-up experiments confirmed that the two photocatalysts, especially the YInO(3), had excellent photocatalytic activity for toluene oxidation and water splitting under visible-light irradiation.
