碳布基底NiO纳米片阵列结构的制备及电化学性能表征

Preparation and Electrochemical Performance of Carbon Cloth-based NiO Nanosheet Arrays

为解决镍基电极材料导电性差、材料利用率低和结构稳定性较差导致应用受到限制的问题,采用水热法在碳布基底制备Ni(OH)_(2)前驱体,并进一步热处理生成NiO纳米片阵列。在制备前驱体的过程中,通过改变氨水的滴加量,改变水热反应溶液的pH值,研究了pH值对NiO纳米片阵列形貌及性能的影响。

The application of nickel-based electrode materials is limited due to poor conductivity,low material utilization and poor structural stability.To solve that,the hydrothermal method is used to prepare Ni(OH)2 precursor on carbon cloth substrate,and further heat treatment is carried out to generate NiO nanosheets arrays.In the process of preparing the precursor,the effect of pH on the morphology and performance of NiO nanosheets is studied by changing the amount of added ammonia water and the pH of hydrothermal reaction solution.
