氧化锌纳米晶须的燃烧合成
ombustion Synthesis of Zinc Oxide Nanowhiskers
以锌（Zn）粉为原料，氧化锌（ZnO）粉为稀释剂，硝酸铵（NH4NO3）为添加剂，利用空气中的燃烧合成法制备出形貌良好的ZnO纳米晶须，其平均直径约为100nm，长度不超过10μm。探讨了ZnO稀释剂及NH4NO3添加剂对燃烧反应过程、产物形貌及晶须生长的影响。结果表明，ZnO稀释剂和NH4NO3添加剂都能起到为空气中的氧气提供渗入通道及降低体系燃烧温度（防止Zn粉熔化）的作用，同时NH4NO3也是一种有效的形貌控制剂，可促进ZnO一维纳米结构以气-固方式进行生长。
In this paper, zinc oxide (ZnO) nanowhiskers were successfully fabricated via a combustion synthesis method by using Zn, ZnO and NH4NO3 powders as raw materials. The ZnO nanowhiskers have diameters about 100 nm and a length of no more than 10 micrometers. The effects of ZnO and NH4NO3 on the combustion reaction process, morphology of the products and the growth of the nanowhiskers were investigated. It was found the both of ZnO and NH4NO3 can provide the pathway for the air infiltration and decrease the combustion temperature to prevent the Zn melting. In addtion, NH4NO3 was an effective morphological-control agent for the one-dimensional ZnO nanostructures growth through vapor-solid mechanism.
