摘要：

The electrochemical behaviour of basal single crystal Pt electrodes in an alkahne medium (0.1 M NaOH) has been studied. The voltammogram for the Pt (111) surface orientation shows two clearly defined zones. One corresponds to weak hydrogen adsorption states and the other could be tentatively assigned to strong hydrogen adsorption states. The voltammogram for a Pt (100) surface shows four different hydrogen states while for the Pt (110) orientation only one hydrogen state is obtained. In this medium the Pt (110) surface does not undergo reconstruction. © 1990.
