A wide visible-light-responsive tunneled MgTa2O6−xNx photocatalyst for water oxidation and reduction†
Abstract
We demonstrate for the first time that a nitrogen-doped tunneled oxide MgTa2O6−xNx with an absorption edge of ca. 570 nm can drive both water oxidation and reduction half reactions in the presence of scavengers under visible light irradiation, showing great potential in solar water splitting.
