Silver nanoparticles anchored reduced graphene oxide for enhanced electrocatalytic activity towards methanol oxidation

摘要

Graphical abstractDisplay OmittedHighlights?Homogeneous anchoring of silver nanoparticles on reduced graphene oxide (rGO/Ag).?Application of rGO/Ag as an electrocatalyst for methanol oxidation.?Improved electrocatalytic activity is due to synergetic interactions of Ag NPs and rGO sheets.AbstractIn this report, silver nanoparticles (Ag NPs) anchored reduced graphene oxide (rGO) sheets (rGO/Ag) nanohybrid has been explored as anode material in direct methanol fuel cells (DMFCs). The synthesized rGO/Ag nanohybrid is characterized by XRD, XPS, FTIR spectroscopy and HRTEM techniques. Cyclic voltammograms demonstrate that the rGO/Ag nanohybrid exhibits higher electrocatalytic activity in comparison to rGO sheets f
