Hydrothermal synthesis of C-doped Zn3(OH)2V2O7 nanorods and their photocatalytic properties under visible light illumination

▶ A visible-light-driven photocatalyst, C-doped Zn3(OH)2V2O7, prepared by a hydrothermal method was firstly studied. ▶ The catalyst exhibited efficient photocatalytic activity in the degradation of methylene blue under visible-light irradiation. ▶ The carbon existing on the surface of Zn3(OH)2V2O7 nanorodes is free and carbide formation.
