IN-SITU TRANSMISSION INFRARED REACTION CELL UNDER EFFECT OF JET PLASMA AND TEST METHOD

WIPO Patent Application WO/2023/082396

A1

An in-situ transmission infrared reaction cell under the effect of a jet plasma and a test method, relating to an infrared spectral analysis test system. The in-situ transmission infrared reaction cell comprises: a cell body (1), a base (3) being provided inside the cell body (1), a sample holder being provided on the base (3), and the sample holder being used for placing a sample (10); and a jet plasma generating device (2) comprising a high-voltage electrode (14), a grounding electrode (15), a wire (16), and an insulating layer (17), wherein the high-voltage electrode (14) and the grounding electrode (15) are provided on the cell body (1) and are insulated from the cell body (1), a potential difference is formed between the high-voltage electrode (14) and the grounding electrode (15), a gas is converted into plasma between the high-voltage electrode (14) and the ground electrode (15), and the plasma gas acts on the sample (10). Jet plasma is used as a plasma source which is placed in the in-situ transmission infrared reaction cell and acts on the sample (10) in real time during an infrared spectroscopy process. The present invention has the characteristics of stable discharge, no contact with a catalyst sample, and a compact and simple structure.
