摘要: 石墨具有很好的导电性和化学稳定性而被广泛地用作电极材料,细粉状石墨对氧的电化学还原表现出相当好的催化活性[1],氧在碳上的还原机理已经有许多人进行过研究[2,3],本工作中利用在真空条件下高速振动制备了超细振动球磨石墨,并运用旋转盘环电极技术研究了氧在这种石墨上的电化学还原机理。

Abstract: Oxygen reduction on rotating ground ultrafine graphite ring-disk electrode has been investigated in alkaline solution. The results show that ultrafine graphite is a good catalyst for O2 reduction to hydrogen peroxide. The peroxide ion not only isn't reduced further but also isn't decomposed by catalysis on the ground graphite.

Key words: Oxygen cathode, Graphite cathode, Electrocatalysis
