研究了铝在脱氧的3.5%NaCl电解液中不同阳极电位下的析氢和溶解过程,为铝的负差效应(NDE)提供了新的认识。创新以前的报告,溶解的Al 3+离子的瞬时浓度检测使用一种新的原位电化学ICP-OES技术和溶解的化学计量n = 3,观察到,从而排除了铝中间体离子机制。定量研究了局部pH值和表面膜破裂面积对析氢速率的影响,表明铝的无损检测是这两个因素综合作用的结果。
Hydrogen evolution and dissolution of Aluminium (Al) have been investigated at different anodic potentials in de-oxygenated 3.5 % NaCl electrolyte to afford new insights into its negative difference effect (NDE). Innovatory to previous reports, the instantaneous concentration of dissolved Al3+ions was detected using a novel in-situ electrochemical ICP-OES technique and a dissolution stoichiometry of n = 3 was observed, thereby precluding the Al intermediate ion mechanism. The effects of the local pH and the surface film’s breakdown area on the hydrogen evolution rate were investigated quantitatively, which suggests that the NDE of Al results from the combined effects of these two factors.
