Vertical NiPS3 nanosheets in situ grown on conducting nickel foam were fabricated by a facile one-step chemical vapor transport method and used as an efficient bifunctional catalyst for overall water splitting.
10%CoO/g-C3N4 exhibits good photocatalytic performance under visible light irradiation without any sacrificial reagents.
A Si-doped Ir electrode can be used as a bifunctional catalyst for overall water electrolysis in acidic media.
