微/纳米结构的镍、钴氢氧化物在能量存储、传感器、催化及电致变色等领域有着广阔的应用前景。氢氧化镍和氢氧化钴的性能与材料的形貌、结构、尺寸、组成等参数密切相关。本文从产物形貌的角度介绍了近年来不同形貌微/纳米结构镍、钴氢氧化物的研究现状,比较分析了三维结构(花状球形结构、空心球、其他特殊形貌)、二维结构及一维结构镍、钴氢氧化物的制备方法和形成机理。
Micro / nano structure of nickel, cobalt hydroxide in the energy storage, sensors, catalysis and electrochromic and other fields have broad application prospects. The properties of nickel hydroxide and cobalt hydroxide are closely related to the material morphology, structure, size, composition and other parameters. In this paper, the current research status of micro / nanostructured nickel and cobalt hydroxides with different morphologies in recent years is introduced from the perspective of product morphology. Three-dimensional structures (flower-shaped spherical structure, hollow sphere and other special shapes) Structure and one-dimensional structure of nickel, cobalt hydroxide preparation and formation mechanism.
