On-Surface Polymerization of In-Plane Highly Ordered Carbon Nitride Nanosheets toward Photocatalytic Mineralization of Mercaptan Gas

Fangsong Guo et al.

Summary: 2D carbon nitride nanosheets with in-plane highly ordered structure (PCNNs-IHO) are successfully prepared by on-surface polymerization of melamine on NaCl crystal surface at elevated temperatures. The NaCl crystals with relative high surface energy facilitate the adsorption and activation of melamine to undergo condensation reaction, and also function as unique substrates to orientate the assembly of 2D nanosheet structure. NaCl acts as a reactant to provide Na+ doping into carbon nitride matrix, affording PCNNs-IHO with robust structural base sites. PCNNs-IHO exhibits superior photocatalytic performance toward CH3SH mineralization under visible light irradiation.
