Abstract

The invention discloses a thin-electrolyte-layer electrochemical reaction tank suitable for in-situ infrared detection. The electrochemical reaction tank comprises a base, a round liquid storage groove, a round planar BaF2 window flake and an upper round cover, and the thin-electrolyte-layer in-situ reaction tank with a solution self-supply function is formed by communication design of a solutionchamber and the liquid storage groove in an assembly mode of directly attaching the window flake to a working electrode on the base. By means of direct attachment of the working electrode and the window flake, thickness of a liquid layer in the solution chamber can be reduced, and extra loss of an infrared light signal in a measuring process is greatly reduced. Meanwhile, with the adoption of thecommunication design of the solution chamber and the liquid storage groove, loss of a reaction liquid in the solution chamber can be supplied in real time in the in-situ infrared measuring process. Areal and reliable in-situ measurement environment can be provided for chemical reaction process research of the electrode surface of a solid-liquid system, loss of the infrared light signal in the measuring process can be obviously reduced, and reliable infrared spectral information with high signal-noise ratio of the electrode surface can be obtained.

Description

technical field [0001] The invention relates to the technical field of infrared spectrum detection and analysis, in particular to a thin liquid layer electrochemical reaction cell suitable for in-situ infrared detection. Background technique [0002] In the energy conversion process of the surface and interface of energy materials, the detection of surface structure and key intermediate products is very important for the optimization and improvement of material performance and the study of the mechanism of catalytic process. Infrared spectroscopy is an important fingerprint technology for the characterization of physical properties in the fields of chemistry, materials, energy, biology, and the environment. It plays an important role in the detection of surface and interface structures and the identification of surface functional groups. However, due to the strong absorption of infrared light in aqueous solution (the absorption length of water to infrared spectrum is usually...
