Hydrothermal Synthesis and Photo Catalytic Properties of Cu3Mo2O9 for the Degradation of Rhodamine B

A Cu3Mo2O9 photo catalyst was successfully prepared by hydrothermal synthesis using ammonium molyb date and cupric nitrate trihydrate as the starting materials. The material thus obtained was characterized by X-ray diffraction, transmission electron microscopy (TEM), as well as ultraviolet–visible (UV-Vis) and Fourier-transform infrared (FTIR) spectroscopy. The photo catalytic activity of Cu3Mo2O9 was evaluated for the degradation of Rhoda mine B (RhB) : the degradation efficiency reaches approximately 89.2% in 60 min at room temperature with an average activation energy of the reaction system is 44.79 kJ·mol‾1, for the reaction system. This result suggested that the Cu3Mo2O9 photo catalyst exhibits excellent absorption and photo catalytic activity for RhB.
