摘要 对化学水浴法制备的六方纤锌矿ZnO纳米棒,分别采用Ag、NiO以及CuO纳米颗粒进行了表面修饰处理,研究了表面修饰对ZnO纳米棒的气敏选择性、敏感性的作用.结果表明,经过表面修饰的ZnO纳米棒的气敏综合性能有了显著的改善,不仅材料的灵敏度得到了明显提高,而且,CuO修饰的ZnO纳米棒对硫化氢气体有很高的选择性. ZnO nanorods with hexagonal wurtzite structure were synthesized by the facile chemical bath deposition method.In order to alter their gas response towards the various test gases,the surfaces of ZnO nano-rods were decorated with different nanoparticles,such as Ag,CuO and NiO.The gas response and selectivity of the surface modification of ZnO nanorods were investigated.The results showed that their gas sensing perform-ances were improved obviously after the surface decoration.Especially,the ZnO nanorods decorated by CuO nanoparticles have the higher selectivity and sensitivity to hydrogen sulfide gas than the other test gases.
