Polymeric carbon nitride（CN） has been widely studied and applied in the field of photocatalysis benefiting from its visible light response，high chemical stability，low cost，easy preparation and non-toxicity.However，its shortcomings，such as small specific surface area and easy recombination of electron-hole pairs，seriously limit its photocatalytic performance.Co doped CN was prepared by one-step calcination of urea and two widely used cobalt salts[CoCl2 and Co（NO3）2] as precursors，and the effects of different Co sources on the photocatalytic CO2 reduction performance of the products were studied.The results showed that the photocatalytic CO2 reduction performance of CN doped with appropriate amount of Co by using CoCl2 as Co source was improved.The CO generation rate was increased from 82.7 μmol/（g·h）for pure CN to 374.5 μmol/（g·h），and the CO selectivity was increased from 79.1% to 88.5%.By contrast，Co doped CN using Co（NO3）2 as Co source was tended to produce hydrogen，and its photocatalytic CO2 reduction performance was not improved.The photocatalysts were characterized by inductively coupled plasma（ICP），X-ray diffraction（XRD），fourier infrared spectroscopy（FT-IR），X-ray photoelectron spectroscopy（XPS），UV-Vis diffusion reflection spectroscopy（UV-Vis DRS），scanning electron microscopy（SEM），physical adsorption，photoelectrochemical test and etc.，and the material structure and the reasons for the improvement of the photocatalytic performance were analyzed.
