La　doped　alkali　tantalate　photocatalysts　(MTaO3,　M　=　Li,　Na,　K)　were　synthesized　by　solid-state　reaction.　Photocatalytic　reforming　of　glucose　solution　(as　a　model　of　biomass)　over　MTaO3　for　H2　production　were　investigated　and　compared.　NaTaO3　exhibited　the　highest　activity　for　H2　production,　while　LiTaO3　showed　the　lowest　activity.　Adding　glucose　to　water　could　apparently　enhance　the　H　2　evolution　rate　and　suppress　the　generation　of　O2　over　NaTaO3,　whereas　glucose　was　gradually　oxidized　to　CO2.　The　optimum　loading　amount　of　NiO　was　found　to　be　0.2　wt.%　for　NaTaO3,　and　it　was　more　effective　for　H2　production　from　glucose　solution　than　Pt　co-catalyst.　©　2010　Elsevier　B.V.　All　rights　reserved.
