Electrochemical Fabrication of Nano-Structured Poly(dimethoxyaniline)-Platinum Hybrid Materials: An Efficient Anode Electrocatalyst for Oxidation of Methanol
Journal article, 2023

A novel electro-co-deposited nanostructured poly(2,5 dimethoxyaniline) and Platinum (PDMA-Pt) nanocomposite were synthesized via single-step co-deposition by electrochemical method. The as-prepared nanocomposite material Methanol oxidation reaction Morphology was characterized through FESEM. PDMA-Pt shows an average diameter of 150-200 nm. The elemental percentage of PDMA-Pt was analyzed through EDX and mapping images. It shows that carbon, hydrogen, platinum, and oxygen are present in them. Physiochemical properties were characterized by XRD and FT-IR studies. XRD studies show the synthesized material is crystalline in nature. The electrochemical activity of the PDMA-Pt nanocomposite was observed using Cyclic voltammetry (CV), chronoamperometry (CA), and Electrochemical Impedance spectroscopic (EIS) techniques. The Electro-co-deposited PDMA-Pt modified electrode has efficient electrocatalytic activity with lower oxidation potential at 0.87 V and the Methanol oxidation reaction (MOR) stable time is 1500 s in 0.5 M H2SO4 acidic medium. The fabricated PDMA-Pt nanocomposite is capable of an anodic catalyst for direct methanol fuel cell utilization.
