摘要
We report a facile and effective approach for the fabrication of hierarchically porous-structured NiO film. In this approach, the NiO film was deposited by chemical bath deposition through a self-assembled monolayer of polystyrene spheres template. The obtained NiO film exhibits a special hierarchical structure consists of two parts: the lower part is nickel oxide monolayer hollow-sphere array and the upper part is randomly porous net-like nickel oxide. The as-prepared NiO also shows a high specific surface area of 537 m(2) g(-1) and a narrow pore distribution centered at 140 nm. This is a technique for preparing large area hierarchical porous oxide or hydroxide films, which have a great promise for applications in optical devices, electrochemical sensors and thin-film batteries.
