Abstract: Boron doping graphitic carbon nitride used borax,boric acid and boron oxide as boron source.The best doped boron source,the doping temperature and doping ratio were determined by a series of experiments,and the doping treatment method was optimized.The samples were characterized by XRD,UV-Vis,XPS,FT-IR,PL,TEM and SEM.The photocatalytic activity of samples was tested by rhodamine B as degradation pollutant.The results showed that the introduction of boron broadened the response range of visible light,reduced the bandgap width of sample,improved the utilization of visible light,suppressed the recombination of photogenerated electrons and holes,and increased specific surface area.Furthermore,the photocatalytic properties were improved significantly.And the photocatalytic activity of B-CN(1∶6) was the highest,its rate constant of photocatalytic degradation for rhodamine B was 3.1 times of g-C3N4.
