Photoassisted hydrogen production under visible light over NiO/ZnO hetero-system

Belhadi, A.; Boumaza, S.; Trari, M. - In: Applied Energy 88 (2011) 12, pp. 4490-4495

Visible light driven water reduction is successfully achieved over the novel hetero-system NiO/ZnO. The capacitance measurement (C−2–V) of NiO exhibits a positive slope, characteristic of n type conductivity, from which a flat band potential of −0.80 VSCE and a density of 1.41×1018cm−3...
