中文摘要：
引言 过氧化氢是一种多用途绿色氧化剂,目前主要用蒽醌法生产.蒽醌法虽然技术成熟,但过程复杂,装置投资大,生产成本高,且对环境有污染.因此,近年来国外对于以氢气和氧气为原料,直接合成过氧化氢的新方法研究十分重视[1-3].
英文摘要：
The effects of the diameter of high-voltage electrode wire, the voltage of discharge, the structure of reactor and the total flow rate of H2-O2 feed on the direct synthesis of hydrogen peroxide in ambient conditions by the dielectric barrier discharge （DBD） plasma method were studied. The results showed that the diameter of high-voltage electrode wire, the voltage of discharge and the structure of reactor had pronounced effects on H2O2 synthesis. By using a self-designed DBD plasma reactor （recycled flowing electrolyte as grounding electrode）, H2O2 was synthesized with 32.51% yield at room temperature and atmospheric pressure from H2O2 feed, which was several times higher than that reported in literature.
