Synthesis and Photocatalytic Mechanism of Visible Light-Activated LaVO₄/TiO₂ Composite

Abstract:

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.
