采用０．０５ｍｏｌ／ＬＨ３ＢＯ３＋０．０１ｍｏｌ／ＬＣｏＳＯ４溶液，在Ｐｔ（１１１）面上获得了电结晶Ｃｏ利用电化学扫描隧道显微镜（ＥＣＳＴＭ）及反射电子显微镜（ＲＥＭ），观察了不同过电位时Ｃｏ的成膜过程，证实了Ｃｏ在Ｐｔ（１１１）面上的电结晶均为三维岛状生长方式．
Electrocrystallization Co was obtained on Pt (111) surface by using 0.05mol / LH3BO3 + 0.01mol / L COSO4 solution. Electrochemical scanning tunneling microscopy (ECSTM) and reflection electron microscopy (TEM) were used to observe the effect of Co It is confirmed that the electric crystallization of Co on the Pt (111) surface is a three-dimensional island-shaped growth pattern.
