In this study, we report the synthesis of metallic and bimetallic nanoparticle (AgNP, AuNP, and Ag@AuNP)-involved l-cysteine-functionalized reduced graphene oxide nanocomposite (AgNPs/cis/rGO, AuNPs/cis/rGO, and Ag@Au/cis/rGO) and their applications as an electrocatalyst for methanol electro-oxidation. The nanocomposites were characterized by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). Experimental results demonstrated that the prepared nanocomposites enhanced electrochemical efficiency for methanol electro-oxidation with regard to diffusion efficiency, oxidation potential, and forward oxidation peak current.eninfo:eu-repo/semantics/closedAccessMethanol oxidationFuel cellReduced graphene oxideNanoparticleCharacterizationArticle2182285229310.1007/s11581-015-1395-12-s2.0-84938286334Q1WOS:000358665100022Q3
