在300 K时,在吸附CO的影响下,Pt(110)表面通过均匀成核的小“孔”(尺寸约为10 × 10 ~(-2))的重构提升。在350 K时,[110]弦发生更多相关位移,这与逆过程相同,即脱附后1× 2相的恢复。
Lifting of the reconstruction of the clean Pt(110) surface under the influence of adsorbed CO proceeds at 300 K through homogeneous nucleation of small “holes” (with about 10 × 10 Å2 size). At 350 K more correlated displacements of [110] strings take place, a characteristic shared with the reverse process, namely the restoration of the 1× 2 phase after desorption.
