Comparative study of toluene oxidation over reduced graphene oxide-supported Pt and Ni catalysts
Reduced graphene oxide (rGO) was prepared from graphite by modified Hummers oxidation followed by two-step thermal reduction and used as support for Pt and Ni catalysts in toluene oxidation. The protocol produced few-layer rGO with residual oxygenated anchoring groups and with a 23-fold increase in…
