The present work introduces the visible light as an external stimulus and for the first time demonstrates that methanol synthesis over Cu/ZnO catalysts can be effectively promoted by solar energy under atmospheric pressure. Experimental and theoretical studies document that hot electrons were photo-excited by localized surface plasmon resonance (LSPR) on Cu nanoparticles and such photo-excited hot electrons could transfer to ZnO through the metal-support interfaces. The hot electrons on Cu and ZnO synergistically facilitated the activation of reaction intermediates. Consequently, the activation energy was reduced by 40% and the methanol synthesis activity was promoted by 54%. This work provides a new strategy towards synthesis of liquid fuel via CO2 reduction under low pressure and sheds new light on the mechanism of photo-mediated catalysis.Elsevier2019-08-05engjournal articleAMhttp://hdl.handle.net/2115/82439https://doi.org/10.1016/j.apcatb.2019.03.0030926-3373AA1082551XApplied Catalysis B-environmental2501016https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/82439/1/Accepted_%20Manuscript%28Ye%29.pdfapplication/pdf878.31 KB2019-08-05https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/82439/2/Accepted_%20Supplementary%20Material.pdfapplication/pdf624.39 KB2019-08-05
