Improved light absorption and photocatalytic activity of Zn,N-TiO2−x rich in oxygen vacancies synthesized by nitridation and hydrogenation†
Abstract
Zn,N-codoped TiO2 rich in oxygen vacancies (Zn,N-TiO2−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.
