摘要：

InVO4　(50　wt%)　nanocrystals　particles　were　confined　in　the　pores　of　SBA-15　mesostructured　silica　by　using　the　cetyltrimethylammonium　bromide-templated　hydrothermal　strategy.　The　surface　areas,　light　absorption　properties　and　the　thermal　stabilities　of　the　prepared　photocatalyst　could　be　enhanced　by　introducing　the　support　of　SBA-15.　The　resulting　materials　exhibited　higher　photocatalytic　performance　for　H2　production　in　pure　water　under　visible　light　irradiation　compared　with　InVO4/CNTs　or　bulk-InVO4.　And　it　is　found　that　a　mixed　crystal　phases　(monoclinic　and　orthorhombic)　of　InVO4　obtained　at　the　calcination　temperature　of　700°C　maybe　played　important　role　in　determining　the　reaction　activity.　Copyright　©　2009　by　ASME.
