Embodiment 1

[0018] A gold film with a thickness of 100 nm was deposited on the surface of freshly dissociated mica flakes by vacuum evaporation, followed by H 2 SO 4 0.5M, aniline 0.15M solution electrochemically deposited a polyaniline film with a thickness of 50nm on the gold film, washed the polyaniline film with sulfuric acid solutions of pH 1 and 3 in turn, transferred to the spectrum electrolytic cell and injected K 2 SO 4 0.01M, pH3 electrolyte, according to figure 1 Assemble the spectral electrolytic cell in the following way: place the polyaniline-modified electrode in the center of the copper base, connect the electrode to the conductive base with conductive copper tape, then fix the copper base with the polytetrafluoroethylene cavity by bolts, and finally Put the platinum wire electrode and Ag / AgC into the cavity as the counter electrode and reference electrode respectively, connect the inlet of the solution to the peristaltic pump, and connect the outlet to the waste liqu...

Abstract

The invention relates to an electrolytic tank which comprises a metal base, a cavity, a sealing cover and a solution inlet / outlet, wherein the metal base is used for radiating and supporting a work electrode; the cavity is packaged with the base together by virtue of a nut, so that the sealing property of the electrolytic tank is ensured; the sealing cover is used for sealing an electrolyte and preventing the loss of a Raman signal due to liquid evaporation, an optical glass window is formed in the bottom of the sealing cover, and laser vertically passes through the optical window to irradiate the surface of the work electrode, so that the collection of the Raman signal is facilitated; the solution inlet / outlet is connected with a peristaltic pump, so that a solution in the electrolytic tank is immediately updated.

Description

technical field [0001] The invention relates to an electrolytic cell. In particular, the invention relates to an electrolytic cell for Raman spectroscopy. Background technique [0002] Raman spectroscopy is a powerful material characterization technique that can provide molecular structure information of substances. Each Raman vibration peak matches a certain fixed chemical bond, and the Raman scattering of water is very weak. Raman spectroscopy is a research Ideal tool for electrochemical reactions at solid-liquid interfaces. If the Raman spectroscopy technique is combined with the study of the electrochemical electrode reaction mechanism, it can be used to measure the type and concentration of electrochemically active particles in the solution and their changes with time and electrode potential, and to study the kinetics of the electrode process and the electrode electrolyte solution. interface properties. [0003] An ideal Raman spectroscopic electrolytic cell should h...
