pH-dependent interaction of interfacial water with Pt in the electrocatalytic hydrogen oxidation reaction
The electrocatalytic hydrogen oxidation reaction on Pt is orders of magnitude slower in alkaline solutions than in acidic solutions. Here, by measuring the ratio of mass change to charge change for the oxidation of adsorbed hydrogen (Had) in Ar/H2/D2, we show that the oxidative desorption of Had off Pt is coupled with...
