| 英文摘要 | the poor electrical conductivity of mno2 limits its use as an electrode material. to overcome this limitation, we report an easy and rapid approach to deposit nanosized mno2 onto multi-wall carbon nanotubes functionalized with hydroxyl groups (mwcnts-oh) by chemical reduction of kmno4 with mnso4 in aqueous solution under ambient conditions. characterization with xrd and tem reveals that the obtained mno2/mwcnts-oh composite is nanocrystalline and partially covered by mno2 nanosheets with a thickness of 1-3 nm at a mno2 loading of 20 wt%. cyclic voltammetry (cv) and galvanostatic charge-discharge measurements reveal that the mno2/mwcnts-oh composite with a mno2 loading of 20 wt% has a relatively high specific capacitance of 234 f/g at a scan rate of 2 mv/s and exhibits good cycling stability. furthermore, the oxygen reduction reaction (orr) shows that mno2/mwcnts-oh composite may have potential applications as a non-noble metal electrocatalyst in fuel cells and metal-air batteries.
