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/cm(2), corresponding to a Pt coverage of only 0.08-0.16 monolayer. With an overpotential of 65 mV at 20 mA/cm(2), the modified GC hag a HER activity comparable to that of the commercial Pt working electrode.
