This research describes the synthesis of a novel type of poly [cyclotriphosphazene-co-1,3,5-triol nitrobenzene] (PCTNB) microspheres with uniform size and diameter of more than 2 μm having well characterization. These microspheres are further used to wrap the CNTs by a facile route using template based non-covalent method to form [email protected] composite. This composite is further well analyzed before it is subjected to pyrolysis. The direct carbonization of the [email protected] is performed at 600 °C at a rate of 5 °C/min under N₂ atmosphere to render the N, P, O doped carbonized [email protected] having enhanced electronic features to be applied as an ORR electrocatalysts in fuel cells accompanied by TEM, XPS, Raman, FT-IR, TGA and BET analyses. Here, we have designed a metal-free, N, P, O doped ([email protected]) electro-catalyst which exhibit significantly high ORR performance in acidic PEM cells showing much higher onset potential of (0.94 V) and half-wave potential of (0.85 V) with electron transfer number (n) 3.9 at 0.4–0.7 V as compared to other non-metallic electro-catalysts. Thus, ([email protected]) is a metal-free, methanol tolerant carbon-based ORR catalyst, and it opens up new avenues for clean energy generation for affordable and durable fuel cells.
