Abstract：

Ultraviolet　(UV)　light　was　introduced　into　the　process　of　hydrogenation　of　CO　over　Ru/TiO2　catalyst　which　were　prepared　by　a　facile　impregnation-reduction　method.　It　is　found　that　UV　irradiation　can　promote　the　conversion　of　CO　into　CH4　over　Ru/TiO2　at　150-220　degrees　C.　Based　on　the　testing　results　of　XPS,　FT-IR　and　TPSR　for　Ru/TiO2　under　UV　irradiation,　it　is　proposed　that　the　photo-generated　electrons　induced　by　the　band-gap　excitation　of　TiO2　can　transfer　to　Ru　along　with　the　increase　of　surface　electron　density　of　Ru　sites.　This　will　further　promote　the　adsorption　of　CO　and　its　activation　at　Ru　sites,　resulting　in　the　photo-enhancement　of　the　methanation　of　CO.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
