Abstract: A new research system,which allows samples to be transferred rapidly and without contamination between electrochemical environment and ultra-hight-vacuum chamber,has been set up recently. This system is of interest to combine investigations on structure and proporties of solid surface at both solid/liquid and solid/gas interfaces.The prelimiary study of Pt/Biadelectrode at levels of chemical environment and electronic structure demonstrated the success of the system established.The XPS data indicate that two oxidation states of Bi adatom existe on Pt/Biadelectrode surface.The present results give new interpretation of the promoting mechanism of Bi adatom in electrocatalysis.

Key words: Electrochemistry, Electron spectroscopy, Pt/Biadelectrode, Surface chemical states
