摘要：

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.
