The　photocatalyst　TiO(2)　with　a　wormhole-like　mesoporous　structure　and　narrow　pore　distribution　were　successfully　synthesized　using　triethanolamine　as　template.　The　complex　oxides　InVO(4)　with　a　relatively　high　surface　area,　a　visible　light　active　hydrogen-evolving　photocatalyst,　were　obtained　by　means　of　the　templating　hydrothermal　method　with　a　variety　of　surfactants.　InVO(4)　with　wormhole-like　structure　were　fabricated　by　templating　of　cetyltrimethylammonium　bromide.　By　comparing　with　the　non-mesoporous　samples,　the　mesoporous　photocatalysts　exhibited　higher　photocatlytic　hydrogen　evolution　activity　for　water　splitting　in　the　absence　and　in　the　presence　of　oxalic　acid.　Crown　Copyright　(C)　2010　Published　by　Elsevier　Ltd　on　behalf　of　Professor　T.　Nejat　Veziroglu.　All　rights　reserved.
