a FTIR spectra of CoOOH, Au, and Au/CoOOH after benzyl alcohol adsorption and 15 min of He purging. b EQCM frequency response over Au and Au/CoOOH in 1 M KOH or 1 M KOH with 0.1 M benzyl alcohol. Scan rate: 50 mV s−1. c Adsorption energies of benzyl alcohol in the form of alkoxide on CoOOH, Au, and Au/CoOOH, respectively. The optimized geometries of Ph−CH2O−* for CoOOH, Au, and Au/CoOOH are also displayed. The color of each element is yellow for Au, blue for Co, red for O, white for H and gray for C, respectively. d Partial density of states for Au d orbital in Au/CoOOH, and the energy level of π* orbital (LUMO) for benzyl alkoxide. The isosurface of Ph−CH2O−* (* is Au/CoOOH) is also displayed.
