| 中文摘要 | in situ oxidation study of pt(110) and its interaction with co |
| 英文摘要 | many interesting structures have been observed for o(2)-exposed pt(110). these structures, along with their stability and reactivity toward co, provide insights into catalytic processes on open pt surfaces, which have similarities to pt nanoparticle catalysts. in this study, we present results from ambient-pressure x-ray photoelectron spectroscopy, high-pressure scanning tunneling microscopy, and density functional theory calculations. at low oxygen pressure, only chemisorbed oxygen is observed on the pt(110) surface. at higher pressure (0.5 torr of o(2)), nanometer-sized islands of multilayered alpha-pto(2)-like surface oxide form along with chemisorbed oxygen. both chemisorbed oxygen and the surface oxide are removed in the presence of co, and the rate of disappearance of the surface oxide is dose to that of the chemisorbed oxygen at 270 k. the spectroscopic features of the surface oxide are similar to the oxide observed on pt nanoparticles of a similar size, which provides us an extra incentive to revisit some single-crystal model catalyst surfaces under elevated pressure using in situ tools. |
