Abstract
AbstractA simple, environmentally benign, and cost‐effective approach is described to prepare graphene via electrochemical exfoliation of graphite rod from spent batteries. PdNi was deposited on electrochemically exfoliated graphene materials with the electrocatalyst synthesized using a borohydride‐facilitated reduction. Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM) analysis confirmed the exfoliation of graphite from used batteries and deposition of PdNi on electrochemically exfoliated graphenebased material. Cyclic voltammetry results show that the electrocatalytic activity towards ethanol oxidation of PdNi on electrochemically exfoliated graphene oxide (EGO) exfoliated from graphite of used battery has improved compared to carbon black as a support material.
