In this study cobalt tungstate (CoWO₄) nanoparticles decorated over PDMA (Poly 2,5 dimethoxy aniline) are utilized as a novel hybrid nanocomposite for methanol oxidation. The CoWO₄ and PDMA were synthesized using an ultrasonication strategy. The physicochemical characterization such as SEM, HRTEM, XRD, and FT-IR affirmed the presence of CoWO₄ over PDMA matrix. The electrocatalytic activity of the investigated CoWO₄ decorated over the PDMA matrix towards methanol oxidation indicates good performances since the potential is lowered when compared to other materials that are reported. CoWO₄@PDMA hybrid nanocomposite gave methanol oxidation at 0.80 V with a current density of 6.4 mA/cm². The presence of CoWO₄ offered good stability and retention for methanol oxidation reaction. On the whole, the present study will satisfy low-cost and stable transition metal–based nanocomposite for fuel cell applications.
