Abstract

MoSe₂-TiO₂ composites were successfully synthesized via a facile solvothermal method. Their morphology, structure and photocatalytic activity in the reduction of Cr(VI) were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, UV-vis absorption spectroscopy, X-ray photoelectron spectroscopy and electrochemical impedance spectra, respectively. The results show that the introduction of TiO₂ into MoSe₂ boosts the light harvesting efficiency and charge separation and transfer due to their synergistic effect, thus enhancing the visible light photocatalytic activity of MoSe₂ with a maximum Cr(VI) reduction rate of 91% at 120 min compared with pure MoSe₂ (61%) and TiO₂ (5%).
