In this paper,a novel method to fabricate nano-metal electrodes and scanning electrochemical microscopy(SECM) tips has been developed,and fabricated electrodes were characterized by scanning electron microscopy(SEM),cyclic voltammetry and SECM.

Scanning electrochemical microscopy, proposed by A.

Then the basic apparatus,operation mode and application of scanning electrochemical microscopy(SECM) were reviewed in detail.

Electrochemical scanning tunnelling microscope(ECSTM) was used to induce local electrodeposition under mild electrochemical and tunnelling bias conditions.

Single layer growth at underpotential deposition and three dimensional nucleation growth at bulk deposition had been in situ observed by electrochemical scanning tunneling microscopy (ECSTM) at different potentials and times.

A home-built in situ electrochemical scanning tunneling microscope (ECSTM) was applied to investigation of the electrodeposition of Cu on HOPG in CuSO4 solution under potential control.

The molecule orientation and structure can be controlled by applying an electrode potential in electrolyte solution and the formation process can be monitored by electrochemical scanning tunneling microscopy.

As one of the electrochemical scanning probe techniques, the scanning electrochemical microscope (SECM) method can be used to study the dynamic process of the corrosive electrode, and d.

In this paper,various techniques with spatial resolution,such as scanning micro reference electrode(SMET),scanning electrochemical microscope(SECM),atomic force microscope(AFM),and scanning Kelvin probe(SKP),and their applications in corrosion studies were briefly reviewed.
