摘要：Series g-C3N4/Cu/B-TiO2(x) composites with different mass ratio of g-C3N4 to Cu/B-TiO2 were prepared and tested for photocatalytic reduction of CO2. The structure-function relationship of the photocatalysts was investigated through various characterization methods and photocatalytic experiments. The results show that g-C3N4 can be uniformly distributed on the surface of Cu/B-TiO2 and formed a stable heterojunction structure, which effectively reduced the band gap width of the catalyst, thus significantly improving the visible light absorption capacity of the catalyst. The modulation of the composite material properties can be realized by regulating the composite ratio of g-C3N4 and Cu/B-TiO2. The rate and selectivity of photocatalytic reduction of CO2 to produce CO reached the maximum when the mass ratio of g-C3N4 to Cu/B-TiO2 was 3:7, and the rate of CO production was as high as 32.65 mu mol center dot g-1 center dot h-1, which was about 12.87 percentage points higher than that of Cu/B-TiO2.
