Photocatalytic　production　of　hydrogen　from　water　over　semiconductor　materials　is　of　great　interest　from　both　theoretical　and　practical　points　of　view　due　to　its　possible　application　for　converting　solar　energies　into　chemical　ones.　The　mesoporous　photocatalyst　InVO　4　was　synthesized　by　the　template-directing　self-assembling　method.　The　crystal　structure　of　inVO　4　could　be　controlled　by　changing　the　calcination　temperature.　Compared　with　the　anatase　TiO　2　and　conventional　InVO　4　,　the　mesoporous　InVO　4　was　more　responsive　toward　visible　light.　The　evolution　rate　of　H　2　from　water　over　the　mesoporous　InVO　4　achieved　1836　μmole/g-hr　under　UV　light　irradiation,　which　was　much　higher　than　the　anatase　TiO　2　and　conventional　InVO　4　.
