Synthesis and characterization of multi-metallic electrocatalysts withgraphene pencil core substrate for electro-oxidation of alcohols in fuel cells

In this research, silver-platinum bimetallic nanoalloys electrocatalyst was prepared onnitrogen-dop graphene pencil core (NDGPC) by electrochemical deposition method [۱,۲]. Thiselectrocatalyst was characterization by SEM, EDS, and EDS-mapping analysis and was used intwo processes of ethanol electro-oxidation and glycerol electro-oxidation in alkaline media for usein direct ethanol fuel cells (DEFC) and direct glycerol fuel cells (DGFC) [۳]. The synthesizedelectrocatalysts showed good results in terms of potential, current density, and stability for thementioned alcohols. In general, electrochemical synthesis methods have advantages including easysynthesis, no need for high temperature and pressure (synthesis is done at room temperature andpressure), green and pollution-free, etc [۴].
