Photocatalytic material in-situ infrared cell system

Abstract

The invention relates to a photocatalytic material in-situ infrared cell system. The system comprises an in-situ infrared sample transmission cell arranged on a base in a sample chamber of a Fourier transform infrared spectrometer, an external light source, and a gas control system. The in-situ infrared sample transmission cell comprises a cell body, a sample bracket and a heating coil. The sample bracket is arranged in the heating coil. The cell body is provided with a cooling water inlet and a cooling water outlet which are connected with a water cooler. The cooling water inlet and the cooling water outlet are connected together through a condensing coil. A reaction gas inlet and a reaction gas outlet which are connected together through the gas control system are formed in the rear wall of the cell body. An illumination window is arranged on the front wall of the cell body. Transmission windows are symmetrically arranged in the side walls of the cell body. The gas control system comprises a gas distribution system connected with a gas cylinder and a mechanical pump connected with a vacuum tube. The external light source comprises a light source controller, a light source generator and an ultraviolet lamp light source probe. The ultraviolet lamp light source probe is arranged on the illumination window. According to the invention, real-time illumination monitoring can be realized.

Description

technical field [0001] The invention relates to the technical field of photocatalysis, in particular to an in-situ infrared pool system for photocatalytic materials. Background technique [0002] Infrared spectroscopy is an analysis method for determining the molecular structure of substances and identifying compounds based on information such as relative vibrations and molecular rotations between atoms within molecules, and is used in materials science, polymer chemistry, biology, environmental science and other fields. Photocatalysis can use sufficient solar energy to decompose water to produce hydrogen and degrade various organic pollutants, and it can also convert CO 2 Reverting to organic low-carbon fuels is one of the most ideal technical approaches to solve the energy and environmental problems we are facing today. At present, infrared spectrometers can only routinely analyze the molecular structure of photocatalytic materials, but cannot monitor them in real time d...
