Abstract：

A　nanocrystal　heterojunction　LaVO　4　/TiO　2　visible　light　photocatalyst　has　been　successfully　prepared　by　a　simple　coupled　method.　The　catalyst　was　characterized　by　powder　X-ray　diffraction,　nitrogen　adsorption-desorption,　transmission　electron　microscopy,　UV-vis　diffuse　reflectance　spectroscopy,　X-ray　photoelectron　spectra,　photoluminescence,　and　electrochemistry　technology.　The　results　showed　that　the　prepared　nanocomposite　catalysts　exhibited　strong　photocatalytic　activity　for　decomposition　of　benzene　under　visible　light　irradiation　with　high　photochemical　stability.　The　enhanced　photocatalytic　performance　of　LaVO　4　/TiO　2　may　be　attributed　to　not　only　the　matched　band　potentials　but　also　interconnected　heterojunction　of　LaVO　4　and　TiO　2　nanoparticles.　©　2009　American　Chemical　Society.
