本文研究了在硼酸和柠檬酸盐溶液中,异丙胺甲硼烷(IPAB)在金、铂和镍电极上的阳极氧化.着重研究IPAB作还原剂与化学镀中三种金属的催化活性,由三种金属电极的极化曲线分别求出了特征电位、表观活化能、稳定电位.由阳极氧化的电流-电位曲线探讨了IPAB的浓度、溶液的pH值和温度对阳极氧化的影响.在阳极电流密度为1.0×10~(-4)A/cm~2时,由特征电位值计算得出的三种金属对异丙胺甲硼烷阳极氧化的催化活性顺序为:Ni>Au>Pt.此结果与由求得的表观活化能所推论的结果相一致.
In this paper, the anodic oxidation of isopropylamine borane (IPAB) on gold, platinum and nickel electrodes in boric acid and citrate solutions was studied. The catalytic activity of IPAB as reductant and electroless plating of three metals The polarization curves of three kinds of metal electrodes respectively obtained the characteristic potential, apparent activation energy and stable potential.The influence of IPAB concentration, solution pH and temperature on the anodic oxidation was discussed from the anodic oxidation current-potential curves. When the anode current density is 1.0 × 10 -4 A / cm 2, the order of catalytic activity of the three metals calculated by the characteristic potential value for isopropylamine borane anodic oxidation is Ni> Au> Pt. This result is consistent with the inferred result of the apparent activation energy obtained.
