Abstract

The hierarchical NiO microspheres(NiO HMs) assembled from nanosheets were prepared by simple hydrothermal method

and the composite materials doped with diferent proportions of Cu(1.5%

4.5%) were prepared by hydrothermal and calcination method. The structure and morphology of the composite materials were characterized

and the catalytic reduction of CO2 by simulated sunlight was studied. The results showed that the increase of Cu loading was beneficial to the photoabsorption and catalytic stability of the materials. When the doping content was 4.5%

the composite showed the best photocatalytic reduction ability of CO2. The yield of CH_3OH reached 585 μmol/g cat

4 h. In addition

the mechanism of photocatalytic reduction of CO2 was also analyzed.
