A wide visible light driven complex perovskite Ba(Mg1/3Ta2/3)O3−xNy photocatalyst for water oxidation and reduction

A new nitrogen-doped metal oxide photocatalyst Ba(Mg_1/3Ta_2/3)O_3−xN_y (BMTON) with an absorption edge of ca. 560 nm was synthesized, showing obvious H₂ or O₂-evolution half reaction activities under visible light irradiation for promising solar water splitting.
