Aiming to deeply understand the electrocatalytic mechanism of silver on reduction of benzyl
chloride, we carried out an in situ electrochemical surface-enhanced Raman spectroscopic
study to characterize various surface species in different electrode potential regions. A
further analysis with DFT calculation reveals that the benzyl radical and its anionic derivate
bonded on a silver electrode are the key intermediates, implying that the pathway could
drastically differ from the outer sphere concerted electron reduction at inert electrodes.
