A visible-light-driven CeVO4/TiO2 photocatalyst with nanostructured heterojunction has been successfully prepared by a simple coupled method. The catalyst was characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-vis diffuse reflectance spectroscopy (DRS) and spin-trapping electron paramagnetic resonance (EPR). The visible light-induced photocatalytic activities were evaluated by decomposing benzene in gas phase. The result showed that the prepared catalyst exhibited efficient photocatalytic activities with high photochemical stability under visible light irradiation.

In this work, a visible light-activated LaVO4/TiO2 composite photocatalyst has been successfully synthesized via a facile coupled method. The composite was characterized by powder X-ray diffraction (XRD), UV-vis diffuse reflectance spectroscopy (DRS) and spin-trapping electron paramagnetic resonance (EPR). Based on the detection of active oxygen species, a visible light-induced photocatalytic degradation mechanism of benzene on LaVO4/TiO2 was proposed.

In this paper, a wide spectrum responsive LaVO4/TiO2 nanocomposite has been characterized by Laser Raman and X-ray photoelectron spectra (XPS). Strong photocatalytic activities of LaVO4/TiO2 nanocomposite towards the removal of gaseous volatile organic pollutants (typically aromatic compounds) under visible light irradiation were demonstrated. Moreover, applications were also given for the photocatalytic elimination of gaseous benzene under simulated solar light and UV light irradiation.

In this work, a visible light-induced LaVO4/TiO2 composite has been characterized by powder X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) and spin-trapping electron paramagnetic resonance (EPR) to reveal the structure and visible light photocatalytic mechanism for the decompostion of benzene in gas-phase. Based on the experimental results, a visible light-induced photochemical processes on LaVO4/TiO2 are proposed and elucidated.
