Abstract

Abstract:

The C-doped ZnO was prepared by pyrolysis using ZIF-8 as the precursor.In addition,the effect of calcination at 350,400,450 ℃ and aging for 10 min,3 h,24 h of ZIF-8 on in situ preparation of C-doped ZnO were investigated,re-spectively.The morphology and structure of in situ C-doped ZnO was investigated by thermogravimetric（TG）,X-ray diffrac-tion（XRD） and scanning electron microscopy（SEM）.Moreover,the light absorption ability and the dynamics of charge carrier were studied by the UV-vis diffuse reflectance spectra（UV-vis） and photoluminescence spectra（PL） which demonstrated the in situ C-doped ZnO had visible light absorption ability and lower recombination rate of photogenerated carriers.DFT sim-ulation showed that the bandgap value could be effectively reduced by doping C element in the ZnO lattice.The photocatalytic performance of in situ C-doped ZnO was 1.5 and 3.0 times higher than that of pure ZnO under visible light and UV irradiation,respectively.The hole and hydroxyl radicals were the main reactive groups of the in situ C-doped ZnO photocatalytic degrada-tion system,and thus the photocatalytic mechanism of C-doped ZnO was proposed.

Key words: nano-ZnO, C-doping, photocatalysis
