The electrocatalytic reduction of nitric oxide and nitrogen dioxide (NOx) remains a significant challenge due to the need for stable, efficient, cost-effective materials. This study presents novel support system NOx in alkaline media, composed ZrO2-WO3-C (ZWC), synthesized via coprecipitation. Platinum nanoparticles (10 wt.%) were loaded onto ZWC Vulcan carbon support, using similar methods comparison. Comprehensive physicochemical electrochemical analyses (N2 physisorption, XRD, XPS, SEM, TEM, cyclic linear voltammetry) revealed that PtZWC outperformed PtC commercial PtEtek electrocatalysis. Notably, exhibited highest total electric charge reduction. At same time, hydrogen evolution reaction (HER) was shifted more negative cathodic potentials, indicating reduced coverage modified dissociative Tafel mechanism on platinum. Additionally, combination WO3 ZrO2 enhanced electron transfer suppressed HER by reducing NO atom adsorption competition. While incorporation lowered surface area 96 m2/g, it significantly improved pore properties, facilitating better Pt nanoparticle dispersion (3.06 ± 0.85 nm, as confirmed SEM TEM). XRD analysis identified graphite phases, with monoclinic broadening peaks (20–25°). XPS oxidation states Pt, W, Zr tungsten-related oxygen vacancies, ensuring chemical stability catalytic activity.
