Abstract(s) :

(Anglais) In this study, we use two-dimensional black flake nickel oxide as the sensitive material which was synthesized by a facile hydrothermal route. The as-synthesized sheet- like NiO possessed a large specific surface area, as verified by BET characterization. The as- prepared NiO nanosheets had strong absorption in the range of 250–800 nm including UV and visible light. Upon exposure to ppb-level NO 2, the presented sensors showed significant responses under light illumination at room temperature.
