Three-Dimensional Nanoporous Graphene Substrate for Surface-Enhanced Raman Scattering
arXiv:1408.5464 · doi:10.1016/j.matlet.2015.03.131
Abstract
We synthesized three-dimensional nanoporous graphene films by a chemical vapor deposition method with nanoporous copper as a catalytic substrate. The resulting nanoporous graphene has the same average pore size as the underlying copper substrate. Our surface-enhanced Raman scattering (SERS) investigation indicates that the nanoporosity of graphene significantly improves the SERS efficiency of graphene as a substrate as compared to planar graphene substrates.
