a, b In situ Raman spectra of four different catalysts at various potentials (reference to RHE). c CO-DRIFTS measurements of four different catalysts. d Normalized CO peak ratio obtained from c as a function of time. An illustration of the CO-DRIFTS mechanism is inserted at the top. e SVBS measurements of four as-synthesized catalysts.
