UV laser induced photo-response structure-sensitive adsorption of lactic acid on Pt(111)
- 化学化工－已发表论文 
UV irradiation (266 nm) from a nano-second pulsed laser induced a transient photo-current on Pt(111) electrode when it is contacted to an aqueous solution containing lactic acid. The potential dependence of this photo-current and the potentiodynamic behavior in the dark suggested that this electrocatalytic oxidation proceeds under the dual-path mechanism. This photo-response also revealed a potential dependence of the coverage of a short-lived adsorption intermediate. (C) 2002 Elsevier Science B.V. All rights reserved.
