a CV curves of catalysts collected in hydrogen desorption region in N2-saturated KOH solution. b Plot of the area of weak hydrogen adsorption as the index for HBE versus the logarithm of measured exchange current densities. c Polarization curves for i-ZnIn-PR/C in H2-saturated 0.1 M KOH and 0.1 M KOD solution. d LSV curves of i-ZnIn-PR/C and PR/C for HOR in H2-saturated 0.1 M KOH and 0.1 M KOD solution. Inset: mass activity at 50 mV vs. RH(Deu)E. e Scheme for HOR on i-ZnIn-PR/C. In situ DRIFTS spectra of (f) Pt/C and (g) i-ZnIn-PR/C in 0.1 M KOH of 100 ppm CO/H2. h In situ Raman spectra of i-ZnIn-PR/C collected in H2-saturated and CO/H2-saturated (100 ppm) KOH solution (0.1 M). i Scheme for resistance to CO-poisoning of i-ZnIn-PR/C.
