Ordered mesoporous carbon-reduced graphene oxide composites decorating with Ag nanoparticles for surface enhanced Raman scattering

► 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). ► The BET surface area and pore volume of OMC-RGO (361 m2 g−1, 0.23 cm3 g−1) are lower than that of OMC (670 m2 g−1, 0.40 cm3 g−1). ► The Raman signal intensity of OMC-RGO-Ag shows surface-enhanced Raman scattering (SERS) activity.
