Highly efficient hydrogen evolution of platinum via tuning the interfacial dissolved-gas concentration

A facile perfluorooctanesulfonate (PFOS)-modulation strategy was developed to precisely control the dissolved-gas concentration at the electrode/gas/electrolyte interface for enhanced HER. With PFOS modulation, lowered dissolved-hydrogen concentrations at the catalytic interface and sufficient expos...

Summary:A facile perfluorooctanesulfonate (PFOS)-modulation strategy was developed to precisely control the dissolved-gas concentration at the electrode/gas/electrolyte interface for enhanced HER. With PFOS modulation, lowered dissolved-hydrogen concentrations at the catalytic interface and sufficient exposure of the surface active area can be achieved. Accordingly, relative to pure Pt, PFOS-modulated Pt possesses a remarkable HER performance.
