摘要
本文以 α-MnO2 晶型结构为研究基础,通过水热法合成出二氧化锰纳米管状结构.通过研究不同反应时间对纳米管形貌的影响,成功获得α-MnO2纳米管材料的制备条件.同时将所制备出的材料组装成电极,考察水热反应时间对α-MnO2纳米管材料电化学性能的影响,最终确定以浓盐酸与高锰酸钾为反应物,反应温度为150℃,反应时间为6 h时所制备的α-MnO2纳米管材料电化学性能最好.
Abstract
This experiment is based on the study of the α-MnO2 crystal structure,and manganese dioxide nanotubes is synthesized by hydrothermal method.By studying the influence of different reaction times on the morphology of nanotubes,we successfully obtained the preparation conditions of α-MnO2 nanotube materials.At the same time,the prepared materials are assembled into electrodes for electrochemical test.The effect of hydrothermal reaction time on the electrochemical performance of α-MnO2 nanotube materials is investigated.The results indicate that the electrochemical performance of the α-MnO2 nanotube material which prepared with concentrated hydrochloric acid and potassium permanganate as reactants at a reaction temperature of 150℃ and a reaction time of 6 hours is the best.
