Surface configuration of CO adsorbed on nanostructured Pt electrodes probed using broadband sum frequency generation spectroscopy†
Abstract
Using broadband sum frequency generation (BB-SFG) spectroscopy, the effect of surface structure on the adsorption states of linearly bonded CO (COL) on a Pt electrode was thoroughly analyzed. Two overlapped SFG peaks with different linewidths and electrochemical Stark slopes were identified, which correspond to COL in different surface configurations.
