Abstract

A highly active hydrogen evolution reaction (HER) electrode with low Pt loading on glassy carbon (GC) has been prepared by anodic platinum dissolution and co-deposition of polyoxometalates. TEM, EDS, XPS, CV, and ICP-MS analyses gave a Pt loading of 50-100 ng/cm2, corresponding to a Pt coverage of only 0.08-0.16 monolayer. With an overpotential of 65 mV at 20 mA/cm2, the modified GC has a HER activity comparable to that of the commercial Pt working electrode.

摘要

通过阳极铂溶解和多金属氧酸盐的共沉积，在玻碳（GC）上制备了一种低铂负载的高活性析氢反应（HER）电极。透射电子显微镜（TEM）、能谱分析（EDS）、X射线光电子能谱（XPS）、循环伏安法（CV）和电感耦合等离子体质谱（ICP-MS）分析表明，铂负载量为50-100 ng/cm2，仅对应0.08-0.16单层的铂覆盖率。在20 mA/cm2的过电位下，修饰后的玻碳具有与商业铂工作电极相当的析氢反应活性。
