摘　　要：采用尿素和葡萄糖作为前驱物,通过一步热处理方法合成了一系列含氮碳材料(CGCN-X)。利用XRD、FT-IR、XPS、SEM和TEM对合成的CGCN-X进行表征。结果表明:C原子与GCN的主链形成共价键。与纯GCN相比,CGCN-X在过硫酸单盐(PMS)激活下降解双酚A的活性更高,尤其是CGCN-1在30min内对BPA的降解效率高达98%。此外,通过系列实验确定65℃、pH为5时CGCN-1降解BPA效果最佳,淬灭实验表明,在反应过程中^(1)O_(2)是主要的活性氧物种。该种新型含氮碳材料具有强催化活性,可用于活化PMS,在水处理领域具有广阔的应用前景。Series of nitrogen-containing carbon materials(CGCN-X)were synthesized through a one-step thermal treatment process using urea and glucose as precursors.The synthesized CGCN-X were characterized by XRD,FT-IR,XPS,SEM,and TEM.The results indicated that the covalent bonds were formed between carbon atoms and the main chain of GCN.Compared to pure GCN,CGCN-X exhibited higher activity in degrading bisphenol A(BPA)via peroxymonosulfate(PMS)activation.Especially CGCN-1 had a BPA removal rate of up to 98%in 30 min.Furthermore,through series of experiments,the best degradation effect of BPA by CGCN-1 was achieved at 65℃and pH=5,quenching experiments revealed that singlet oxygen(^(1)O_(2))was the dominant reactive oxygen species during the reaction.This novel nitrogen-containing carbon material possesses strong catalytic activity for activating PMS and broad application prospects in the field of water treatment.
