Abstract

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 PCTNB@CNTs composite. This composite is further well analyzed before it is subjected to pyrolysis. The direct carbonization of the PCTNB@CNTs is performed at 600 °C at a rate of 5 °C/min under N₂ atmosphere to render the N, P, O doped carbonized PCTNB@CNTs 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 (C-PCTNB@CNTs) 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, (C-PCTNB@CNTs) 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.
