The synthesis of condensed C-PDA–g-C3N4 composites with superior photocatalytic performance

Carbonized polydopamine-graphitic carbon nitride (C-PDA-g-C3N4) composites have been synthesised via in situ polymerization of dopamine (DA) on the surface of melamine followed by carbonization and condensation for the first time. The obtained C-PDA-g-C3N4 composites display enhanced crystallinity and superior photocatalytic performance.
