Abstract: Aromatic carbon (C) doped graphitic carbon nitride (g-C₃N₄) is one of the effective strategies to improve the photocatalytic performance of g-C₃N₄. The present work developed a feasible method to construct C/g-C3N4 through carbonising the mixture of g-C3N4 and phenol-formaldehyde (PF) obtained in situ polymerisation. This synthesis method not only improves the interaction between PF and g-C₃N₄, but also promotes the preparation of aromatic carbon-doped g-C₃N₄ in the subsequent calcinations process. The resulted C/g-C₃N₄-600 catalysts show developed optoelectronic properties, superior photocatalytic activity and higher surface area (1336 cm² g^-1) due to the extended π-conjugation system and distinctive morphology.

Keywords: C/g-C3N4; optoelectronic properties; surface area; photocatalytic properties; phenol-formaldehyde; polymerisation; surface area; conjugation; morphology.
