摘要：

On-site production method of neutral H2O2 solution by electrolysis of O-2 and water was investigated. Improved SPE (solid-polymer-electrolyte) electrolysis method was applied for the synthesis of neutral H2O2 solution. We found that exposure of a cathode of the SPE electrolysis in O-2 stream (1 atm) was efficient for the neutral H2O2 formation (Exp-SPE method). A cathode prepared from oxidized activated carbon, vapor-grown carbon fiber and PTFE, and coating with Nafion solution was the most active for neutral H2O2 formation. The neutral H2O2 solution of 8 wt% was continuously produced with 27% CE at -0.3 V (Ag/AgCl) by the Exp-SPE method.
