In situ diffuse reflection/in-situ transmission application scenarios
In the field of catalytic research, in-situ diffuse reflectance infrared technology (In situ DRIFTS) is receiving increasing attention from researchers. On the one hand, the infrared characterization method for catalysts is simple, fast, and has almost no consumables (except for normal liquid nitrogen consumption); On the other hand, the method of infrared characterization of catalysts is very mature and has been recognized by many researchers.
At present, the main ways to study catalysts using infrared methods in the market are in-situ infrared diffuse reflection and in-situ infrared transmission. These two methods can provide users with the following information:
Study the chemical reaction kinetics of catalysts
Used for online research on the catalytic performance of catalysts in high temperature, high pressure, or high vacuum environments
Obtain the reaction mechanism and process of catalytic reaction
By conducting adsorption and desorption experiments on probe gas molecules and catalysts at different temperatures, the adsorption active sites and adsorption performance on the catalyst surface can be understood
Effective characterization of the acid-base properties of catalysts
Provide experimental data for the preparation of novel catalysts
Realize component identification and structural analysis of catalyst samples

In situ electrochemical application scenarios
In situ Electrochemical FTIR technology combines the advantages of infrared spectroscopy technology and electrochemical workstations, and can monitor material changes in the electrochemical reaction process in real time, as well as catalytic reactions at the gas liquid solid three-phase interface. It is widely used in environmental, biological, catalytic reaction, and battery research fields. During electrochemical reactions, the structure, valence state, and functional groups of substances undergo changes, which can be detected by infrared spectroscopy signals to reveal reaction mechanisms and kinetic information.
Electrocatalysis and Electrosynthesis
Anodic oxidation reactions (anodic oxidation reactions of methanol, formic acid, ethanol, ethylene glycol, propylene glycol, etc., oxygen evolution reactions, etc.)
Cathodic electroreduction reactions (carbon dioxide electroreduction, nitrogen electroreduction, oxygen electroreduction, nitrate/nitrite electroreduction reactions, hydrogen evolution reactions, etc.)
Photocatalysis and Photosynthesis

Obtain information on the reaction mechanism and kinetics of catalytic reactions

Application scenarios of the analysis and testing center
The testing personnel in the laboratory analysis center often receive various sample testing requirements, such as measuring solid, liquid, and gas samples, or conducting different analyses on samples, transmission or ATR reflection measurements. In this case, replacing different infrared sample accessories is time-consuming and prone to errors. FOLI20-R-T can configure fixed accessories according to customers' actual needs, automatically switch optical paths, and achieve accuracy and efficiency.
