(A) Successive cyclic voltammograms of CaHydA obtained at different temperatures. The data have been normalized to correct for film loss. Vertical dotted lines show the potentials at which the data were taken. B and C show Eyring plots for H+ reduction and H2 oxidation regions, respectively, using data from A. Conditions: pH 6, ω = 2,500 rpm, ν = 5 mV s-1, 100% H2.
