Anatase Mg0.05Ta0.95O1.15N0.85: a novel photocatalyst for solar hydrogen production†
Abstract
Anatase Mg0.05Ta0.95O1.15N0.85, exhibiting a narrow band gap for solar hydrogen, is a promising visible-light-response photocatalyst for photocatalytic or photoelectrochemical water splitting. The excellent photocatalytic activity can be attributed to the satisfying light absorption and electron–hole separation rate.
