Abstract

Carbon materials have attracted considerable interest as metal-free heterogeneous catalysts owing to their superior physicochemical properties, including low cost, stability, and easily tailorable structures as well as excellent catalytic activity. In this study, we have designed an efficient method to produce ultrathin carbon nanosheets (∼2.2 nm) with multi-heteroatom (nitrogen, phosphorus and sulfur) doping and a high surface area (up to 1198 m2 g1). This method employs poly(cyclotriphosphazene-co-4,4′-sulfonyldiphenol) (PZS) as the main carbon source and N,P,S-doping sources, while g-C3N4 nanosheets act as the morphology template, extra N doping source and porogen. The doped carbon nanosh..
