Electrodeposition of Cu2O/g-C3N4 heterojunction film on an FTO substrate for enhancing visible light photoelectrochemical water splitting

g-C3N4 nanoparitcles have been immobilized on a Cu2O film with FTO substrate, resulting in a Cu2O/g-C3N4 heterojunction nanocomposite formation for efficient photoelectrochemical water splitting under visible light irradiation.
