In　this　work,　a　photo-assisted　thermal　catalytic　Fischer-Tropsch　reaction　over　bimetallic　Co-Cu/CeO2　was　constructed.　It　was　found　that　alcohols　can　be　produced　under　3　MPa　at　180　degrees　C　in　the　dark.　Under　light　irradiation,　the　yield　of　alcohol　increased　1.5　times,　and　the　selectivity　was　maintained　at　the　same　temperature.　Based　on　the　XPS　results,　in　situ　H-2-pulse　chemisorption　and　in　situ　diffuse　reflection　infrared　Fourier　transform　spectroscopy　(DRIFTS),　it　is　proposed　that　Co　as　an　active　site　can　adsorb　CO　catalysing　hydrogenation　reactions　to　produce　alcohols.　Under　the　irradiation,　CeO2　generates　photo-generated　electrons　and　transfers　them　to　Co,　so　that　the　electron-rich　density　of　Co　facilitates　the　adsorption　and　activation　of　CO.　Moreover,　the　light　also　induces　Cu　to　produce　localized　surface　plasmon　resonance　(LSPR)　and　excite　hot　electrons,　which　promotes　the　dissociation　of　H-2　and　the　regeneration　of　oxygen　vacancies　on　the　CeO2　surface.　Both　light-induced　behaviors　promote　the　Fischer-Tropsch　reaction.
