A series of Cu/TiO2 were prepared by a modified so-gel methods. Methanol was generated by the photocatalytic reduction of CO2. The maximum methanol yield reached 1000 µmole/g-catal under 28 hours UVC (254 nm) irradiation using 2wt% Cu/TiO2 by CuCl2-1h and CuCl2-3h methods. The Cu+ was the major species on the Cu/TiO2 though multiple chemical status of Cu existed.application/pdf176517 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所光催化二氧化碳Cu/TiO2photocatalysiscarbon dioxide[SDGs]SDG7reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9335/1/912214E002021.pdf
