Abstract

In this study, coenzyme Q10 (CoQ10) has been investigated by in situ near-infrared Fourier transform surface-enhanced Raman scattering (NIR-FT-SERS) spectroelectrochemistry and angle-resolved X-ray photoelectron spectroscopy (AR-XPS) on silver surface. The surface adsorption behavior of the coenzyme Q10 radical intermediate could be monitored by potential-dependent SERS technique. At the applied potential lower than −0.30 V vs.SCE, the radical intermediate CoQ10H˙ stands perpendicularly on the silver surface with both oxygen atoms of the aromatic ring and isoprenoid side chains. When the applied potential is more positive than −0.30 V vs.SCE or at open circuit potential, the quinone ring (benzene ring) of reduced form of coenzyme Q10 (CoQ10H2) adopts a face-on surface configuration on the surface. The responsible mechanism for the potential-dependent SERS spectra is presented. Moreover, the adsorption conformation of CoQ10 has been further confirmed by AR-XPS at the silver surface.
