Abstract：

The　present　work　reports　the　renewable　hydrogen　production　by　an　anaerobic　photocatalytic　reforming　of　glucose,　a　compound　that　could　be　derived　from　biomass,　over　noble-metal-loaded　TiO2　photocatalyst.　The　effects　of　reaction　parameters,　such　as　reaction　atmosphere,　noble-metal　loading,　amount　of　loaded　platinum,　crystalline　phase　of　TiO2,　initial　concentration　of　glucose,　and　the　pH　value　of　the　reaction　solution　on　the　hydrogen　evolution　are　systematically　investigated.　The　results　show　that　the　photocatalytic　H2　production　from　the　glucose　solution　can　be　significantly　enhanced　by　depositing　various　noble　metals　on　anatase　TiO2,　and　the　hydrogen　evolution　rates　are　decreased　in　the　order　Pd　>　Pt　>　Au　≈　Rh　>　Ag　≈　Ru.　For　Pt/TiO2　the　greatest　photocatalytic　reforming　activity　of　glucose　occurs　as　the　Pt　loading　content　of　ca.　1.0　wt.%.　The　presence　of　O2　and　acid　strongly　inhibits　the　hydrogen　production.　The　effect　of　initial　concentration　of　glucose　on　the　hydrogen　evolution　rate　could　be　well　represented　by　the　Langmuir-Hinshelwood　kinetics　model.　A　probable　mechanism　for　the　photocatalytic　reforming　process　was　proposed　and　discussed.　©　2008　International　Association　for　Hydrogen　Energy.　Published　by　Elsevier　Ltd.　All　rights　reserved.
