摘要

把炭黑与PTFE乳液混和制成多孔电极.在用阳离子膜分隔两电极的电解池中

当KOH的浓度大于0.3mol/1时

20℃下产生HO-_2的电流效率超过90%.每公斤过氧化氢耗电2.2kW·h.

Abstract

The porous electrodes were made by admixing PTFE emulsion with carbon black. In the electrolytic cell the cathode and the anode were separated by a ration exchange membrane. The current efficiency of HO2- exceeded 90% at the temperature of 20℃

when the concentration of KOH was greater than 0.3mol/l

the power consumption was 2.2kW·h per kg of H2O2. The steadystate polarization curve was measured.
