The　mesoporous　photocatalyst　InVO4　was　synthesized　by　the　template-directing　self-assembling　method.　The　synthesized　InVO4　was　characterized　by　means　of　X-ray　diffraction,　transmission　electron　microscopy,　N-2　adsorption,　and　ultraviolet-visible　spectroscopy.　The　results　showed　that　the　crystal　structure　of　InVO4　could　be　controlled　by　changing　the　calcination　temperature.　Compared　with　the　anatase　TiO2　and　conventional　InVO4,　the　mesoporous　InVO4　was　more　responsive　toward　visible　light.　The　evolution　rate　of　H-2　from　water　over　the　mesoporous　InVO4　achieved　1836　mu　mol/(g(.)h)　under　UV　light　irradiation,　which　was　much　higher　than　the　anatase　TiO2　and　conventional　InVO4.
