Electrochemical Synthesis of Bi/Pt Bimetallic Nanodentrites for the Electrooxidation of Methanol

摘要

The purpose of this work is to delineate electrooxidation of methanol using hierarchical platinum- bismuth nanodentrites as an electrocatalyst. Potentiostatic electrochemical method was applied toprepare the nanostructures. The shape of nanostructures was controlled by varying the concentration of23+ Pt Cl6 ions in fixed Bi ions and reaction time. The prepared nanocomposites were characterized bySEM, EDX, XPS and CV techniques. The electrocatalytic activity of Pti nanodentrites was studiedtowards methanol oxidation. The prepared nanostructures are simple, eco-friendly and with highelectrocatalytic activity.
