Abstract：

Pt　nanoparticles　were　loaded　on　anatase　TiO　2　by　the　photodeposition　method　to　investigate　their　photocatalytic　activity　for　H　2　evolution　in　an　aqueous　solution　containing　a　certain　amount　of　ethylene　glycol　(EG)　as　the　sacrificial　agent.　The　surface　properties　and　chemical　states　of　the　Pt/TiO　2　sample　were　characterized　by　X-ray　powder　diffraction　analysis,　Brunauer–Emmett–Teller　surface　area　analysis,　transmission　electron　microscopy,　X-ray　photoelectron　spectroscopy,　electron　paramagnetic　resonance,　and　electrochemical　resistance.　The　aqueous-phase　photocatalytic　EG　reforming　using　Pt/TiO　2　and　anatase　TiO　2　generated　not　only　H　2　and　CO　2　,　but　also　CO,　CH　4　,　C　2　H　6　,　and　C　2　H　4　.　Moreover,　the　amount　of　formate　and　acetate　complexes　in　the　solution　increased　gradually.　The　EG　adsorption　and　gas-phase　intermediates　during　photocatalytic　reaction　processes　were　investigated　by　the　in　situ　FTIR　spectrum.　Finally,　the　photocatalytic　EG　reforming　reaction　mechanism　was　elucidated.　This　helped　to　better　understand　the　role　of　a　sacrificial　agent　in　a　photocatalytic　hydrogen　production.　©　2016　Elsevier　B.V.
