Abstract

Zn,N-codoped TiO₂ rich in oxygen vacancies (Zn,N-TiO_2−x) was synthesized by nitridation and hydrogenation of a zinc titanium precursor for the first time, which expands the visible light harvesting region and improves the photocatalytic activity compared to the Zn,N-TiO₂ sample without hydrogenation.
