摘　　要：NiO作为一种重要的无机功能材料具有重要的用途。比较了制备纳米NiO常用的几种方法的优劣。阐述了浓度、反应体系的pH值、所选沉淀剂、热处理温度等制备条件对纳米NiO粒径的影响，概述了纳米NiO作为催化剂、电池电极、超电容器活性电极材料、气敏传感器、电致变色材料等方面的应用。在纳米NiO气敏传感器方面。国内还处于空白阶段；有关NiO降解染料废水的研究，在国内外的报道还很少，这是一个新的领域，有待进一步的研究。As an important inorganic functional material, NiO is very available. In this paper, the general methods of preparation of nano-NiO are compared. Some condition which can influence the grains diameter of nano-NiO are elaborated. These conditions contain solufion＇s concentration, the pH value of the reactions system, the chosen precipitator and the temperature of heat treatment and so on. In the paper, it is summarized that nano-NiO is widely used in many aspects, such as catalyst, battery electrode, capacitor, active electrode material, gas-sensing, electrocolorchanging material. Demestic research on nanoNiO decomposing dyes waste water have rarely been reported. This is a new domain and it is waiting for further research.
