Embodiment Construction

[0020] The specific structure of the device is mainly composed of an electrolytic cell, a reference electrode, a counter electrode, a silicon semi-cylindrical (internal reflection mode) and a calcium fluoride semi-cylindrical (external reflection mode). The silicon half cylinder and the calcium fluoride half cylinder have a diameter of 20 mm and a height of 25 mm. The specific preparation steps are as follows, (1) Internal reflection mode:

[0021] ① First, gold nano-film is chemically plated on the surface of the silicon wafer, and then a platinum film layer is electroplated on the surface of the gold nano-film as a working electrode. ②The surface of the platinum thin film electrode is covered with a silicon rubber ring to prevent the electrolyte from overflowing, and it is put into the electrolytic cell. ③ Insert the reference electrode and the counter electrode into the electrolytic cell, which constitutes the three-electrode system for electrochemical spectroscopic testin...
