DOI: 10.1016/j.actamat.2019.12.007
Abstract: Abstract Oxynitrides are considered as new potential candidates for photocatalysis due to their lower bandgap compared with traditional oxide photocatalysts. However, the formation of native nitrogen monovacancies during the synthesis of oxynitrides reduces their photocatalytic… read more here.
