摘要
The C3N4/Ag composite nanosheets were facilely prepared via an in sire reduction process and Ag nanoparticles were well dispersed on the surface of C3N4 nanosheets. The unique two-dimensional structtlre and strong interactions between C3N4 nanosheets and Ag nanoparticles contributed the good surthce-enhanced Raman scattering（SERS） property due to the electromagnetic field enhancement. In addition, the as-prepared CaN4/Ag composite nanosheets could be used as catalysts or photocatalyst for the degradation of methylene blue（MB） in the presence of NaBH4 or under visible light. Therefore, a facile SERS monitoring of the catalytic and photocatalytic degradation process of MB and the determination of the reaction kinetics were developed.
