▎ 摘  要

Ordered mesoporous carbon-reduced graphene oxide (OMC-RGO) composites are prepared through organic-organic self-assembly method. The conductivity of OMC-RGO (32.5 S m(-1)) is higher than that of OMC (0.76 S m(-1)), while the pore structure is reduced and the BET surface area and pore volume of OMC-RGO (361 m(2) g(-1), 0.23 cm(3) g(-1)) are lower than OMC (670 m(2) g(-1), 0.40 cm(3) g(-1)). Furthermore, the presence of RGO in OMC-RGO is favorable to load more Ag nanoparticles due to the oxygen-containing groups on the surface of RGO and the Raman signal intensity of OMC-RGO-Ag is greatly increased comparing with OMC-Ag, showing surface-enhanced Raman scattering (SERS) activity.
