摘 要:本文通过对H2O2分解动力学性质的研究与溶液表面张力及稳态极化曲线的测定,探讨了H2O2在NiSO4-Na2SO4-NaCl-H3BO4体系中的行为以及H2O2抑制氢气生成的根本原因,并提出有H2O2存在时,氢在镍电极表面放电符合均相平行转化机理。
Abstract: This paper has discussed the behaviour of H2O2 in nicked sulphate solution and the reason for H2O2 to inhibit the formation of hydrogen in NiSO4-Na2SO4- NaCl-H3BO4 system, based on the study of H2O2 decomposition kinetic property, the measurement of surface tension of the solution and the steady-state polarization curves. The paper pointes out that when there is H2O2 in solution, hydrogen dis- charge is in accord with the mechanism of homogeneous parallel transform.
