Preparation and Electrochemical Properties of α-MnO2 Nanotube Materials
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.
