研究前驱物浓度、超重力大小、反应时间、反应温度和反应介质体系的条件对Co3O4前驱物形貌的影响,发现制备花状Co3O4前驱物的最优条件是Co(NO3)2·6H2O和CO(NH2)2在1000/g超重力场、溴苯/水溶液体系、100℃条件下水热反应反应30min,通过前驱物的热分解制得Co3O4,采用SEM和XRD对样品的形貌和物相进行表征。将Co3O4粉末分别与乙炔黑、聚四氟乙烯(PTFE)按一定质量比混合压在镍网上,制成电极片,通过CV测试其电性能,结果发现超重力越大,制备的材料的交流阻抗值越小。

This paper aims to research the effect of the precursor concentration, hypergravity, reaction time, reaction temperature and conditions of reaction medium system on the formation of the precursor of Co3O4. The results show that the optimal condition is that Co(NO3)2·6H2O and CO(NH2)2 react for 30min in the 1000/g hypergravity field and aqueous/bromobenzene solution at the temperature of 100℃. The Co3O4 powder is obtained through thermal decomposition of its precursor. The forms and phases of samples are characterized through SEM and XRD. The electrodes can be made through mixing Co3O4 , acetylene black and PTFE according to certain quality proportion and its electrical performance can be examined through CV. The bigger the hypergravity is, the smaller the value of the AC resistance is.
