Description

Silica sol-gel and aerogel substrates were synthesized using a modified acid catalyzed hydrolysis of tetramethyl orthosilicate method that incorporated graphene oxide and silver nanoparticles into the matrix. The effectiveness of loading of graphene oxide was monitored by UV-vis and surface enhanced Raman spectroscopy (SERS). Characterization data suggests that graphene oxide is detectable through SERS while integrated into a sol-gel and that size of silver nanoparticles has an impact on the SERS spectrum of graphene oxide.
