摘要：

Hydrogen adsorption on Pt(100), Pt(1111)(6(100) x (111)), Pt(110) and Pt(111) electrode surfaces was studied by both volammetry and in situ infrared reflection absorption spectroscopy. The terminal hydrogens adsorbed on Pt(100), Pt(1111) and Pt(110) electrodes were observed at 1990-2080 cm-1 as bands appearing at potentials more negative than 0.25, 0.1 and 0 V versus SHE, respectively. However, a well-oriented pt(111) electrode did not give a significant absorption of the terminal hydrogens under similar conditions. The terminal hydrogen adsorption was sensitive to the surface crystallographic orientation.
