通过在ZnO分级结构上生长NiO纳米颗粒，成功制备了p型NiO/n型ZnO异质结构。采用化学浴沉积法制备了花状ZnO，并以其为载体生长出立方相NiO颗粒。所得异质结构对橙子的光催化降解活性远高于纯NiO、ZnO及其物理混合物，这归因于p-n异质结的形成。
The successful fabrication of p-type nickel oxide (NiO)/n-type zinc oxide (ZnO) heterostructures was achieved by growing NiO nanoparticles on ZnO hierarchical structures. Flower-like ZnO was developed by chemical bath deposition and used as a support to grow cubic NiO particles. The photocatalytic activity of the as-obtained heterostructures for the degradation of methyl orange was much higher than that of pure NiO, ZnO and their physical mixture, which could be ascribed to the formation of p–n heterojunctions.
