From: Tailoring a local acid-like microenvironment for efficient neutral hydrogen evolution
a The LSV curves of Ir–HxWO3 before and after poisoning metallic Ir sites and WO–H sites, respectively. b The Tafel slope comparisons of Ir–HxWO3 before and after poisoning experiments. c The LSV curves of Ir–HxWO3 in 1.0 M PBS (H2O and D2O) electrolyte. d Calculated KIE values (JH2O/JD2O) under 100 mV overpotential. All electrochemical data were corrected for 95% iR drop.
