[SERS and electrochemistry studies on the structure of thiourea adsorption layer on silver electrode].
The structure of thiourea adsorption layer on silver electrode was studied by SERS and electrochemistry. It was found that the thiourea can be adsorbed on the electrode surface and can inhibit the reaction of hydrogen separation. And a change in structure of the thiourea adsorption layer on electrode surface took place at the voltage of about -0.6V. The further SERS experiment showed that the thiourea adsorption layer has a loose structure at about -0.9V and a compact structure at about -0.3V - -0.5V. The transition region is at about -0.6V - -0.8V.
