| 内容記述 | In situ scanning tunneling microscopy (STM) was employed to examine the surface structures of Au(111), Au(100), and Au(110) single crystals in propylene carbonate (PC) containing tetrabutylammonium perchlorate (TBAP). All three electrodes exhibited potential-induced phase 10 transition between the reconstructed and unreconstructed (1 ´ 1) structures at negative and positive potentials, respectively. The potential-induced phase transition of the Au electrode surfaces is attributed to the interaction of TBA cation and perchlorate anion at the electrode surface, which is similar to that which takes place in aqueous solutions. In addition to static atomic structures, dynamic processes of both the reconstruction and the lifting of the reconstruction were investigated 15 by means of in situ STM. The lifting of reconstructed Au(111)–(Ö3 ´ 22) on Au(111) to the (1 ´ 1) structure is completed within 1 min at a positive potential. The diffusion of Au atoms on Au(100) plane in the PC solution proceeds more rapidly than that in the aqueous solution, suggesting that the PC solvent plays an important role in accelerating the diffusion of Au atoms. |
