Fabrication of polymer carbon nitride with organic monomer for effective photocatalytic hydrogen evolution

Abstract

Utilization of solar heat radiation into chemical energy is attributed to semiconductor photocatalyst under sunlight perspective considered as a reversing inspired approach that exacerbates the environmental problems. Recently, our group indicates graphitic carbon nitride (g-CN) by a progressive molecular aggregation co-polymerization process that propagated with a nanoscopic organic conjugated heterocyclic monomer to enhance its photocatalytic activity. This work aims to present a facile induced co-condensation technique and used 2, 6-Furandicarboxylic acid (FA) monomer as demonstrator within g-CN that boosting the photocatalytic properties under solar energy driven caused the reduction of water. The as-prepared samples were demonstrated for various characterizations along with computational evaluation of pure and doped g-CN. The result signifying the integration of organic FA monomer in the triazine core shell of g-CN restoring a substantial delocalization in its π-conjugated system. Meanwhile, after this alternation, an identifiable undulation occurred in the surface area, electronic structure, calculated band gap, chemical composition analysis of g-CN, and also improved its electronic generation process under the visible light radiance. Besides, this unrepeatable integrity of FA co-monomer with ing-CN matrix considerably enhanced the photocatalytic activity toward Godspeed and as such, the superior photocatalyst CN/FA12.0 stimulated a tremendous photocatalytic activity of water reduction with 10.6 enhanced catalytic performances as a contrast of pristine sample respectively.
