通过一步热聚合法制备纳米碳颗粒/氮化碳复合材料，利用XRD、FTIR、TEM、DRS、PL等手段对纳米碳颗粒/氮化碳进行了系统表征，并考察其光催化降解罗丹明B的光催化性能。结果表明，纳米碳颗粒的负载可以显著改善复合材料的可见光吸收能力及光生电子/空穴的分离效率，当加入纳米碳颗粒的质量为10 mg时，所得到的纳米碳颗粒/氮化碳2在20 min内对罗丹明B的降解率可以达到96.5%，明显优于纯氮化碳材料。此外，纳米碳颗粒/氮化碳复合材料还表现出良好的稳定性。

Nanocarbon particles/carbon nitride composite was prepared through one step heat polymerization method. XRD, FTIR, TEM, UV?vis DRS, PL and other methods were used to systematically characterize nanocarbon particles/carbon nitride. Rhodamine B solution was degraded to measure its photocatalytic performance. The results show that the loading of nanocarbon particles can obviously improve visible light absorbed ability of the composite material and the separation efficiency of photogenerated electrons/holes. When the added mass of nanocarbon particles is 10 mg, the rhodamine B degradation rate of as?prepared nanocarbon particles/carbon nitride 2 is 96.5% in the 20 min, which is obviously better than bare carbon nitride. In addition, nanocarbon particles/carbon nitride composites show good stability.
