Abstract

The invention relates to an in-situ infrared spectrum pool for researching a gas-solid interface or a liquid-solid interface. The in-situ infrared spectrum pool comprises a pool body, wherein a gas or liquid inlet/outlet is formed at the upper end of the pool body; a thermoelectric coupler is inserted into the pool body from the upper end of the pool body; an opening is formed at the lower end of the pool body, and the pool body is connected with a base; an infrared crystal is arranged at a joint of the inner part of the base and the pool body; a sealing ring is arranged between the pool body and the infrared crystal; and a light inlet and a light outlet are formed on the base. By adoption of the in-situ infrared spectrum pool, the absorption, desorption and reaction of molecules of gas or liquid on the surface of a solid material can be researched in situ.

Description

technical field [0001] The invention relates to an in-situ infrared spectrum measurement device, in particular to an in-situ infrared spectrum pool used for the research of gas-solid interface or liquid-solid interface. Background technique [0002] In situ infrared spectroscopy is an important analytical tool for studying the reaction and phase transition of solid materials themselves, as well as the interaction between gases or liquids and solid materials. The in situ infrared spectroscopy cell is essential for in situ infrared spectroscopy characterization device. For the study of the gas-solid interface system, in order to avoid the influence of the gas phase signal on the surface signal, the infrared spectroscopy experiment generally needs to be carried out under vacuum conditions, which is difficult to study the gas flow system, and most of the actual gas-solid catalytic reaction system uses flow system. For the study of liquid-solid interface systems, especially the...
