Abstract
Nano‐sized (i) N‐doped sodium trititanate and (ii) N and Cu2+ (Ag+) co‐doped sodium trititanates CuTi3NO6−x (Ag2Ti3NO6−x) were prepared by a solid‐state and ion‐exchange methods, respectively. The materials were characterized by EDS, PXRD, XPS, FESEM, TEM, UV–visible DRS, and Raman spectroscopy. All the materials were crystallized in monoclinic lattice with P21/m space group. The bandgap energy of all the samples was deduced from their UV–visible DRS profiles. Visible‐light‐induced photocatalytic oxidation of the methylene blue (MB) and methyl orange (MO), cyclohexene and phenol, was examined. The Ag+ co‐doped trititanate exhibited the highest photocatalytic activity among the materials investigated.
