Abstract

The invention discloses a photothermal catalytic carbon dioxide reaction detection apparatus and a photothermal catalytic carbon dioxide reaction detection method. The apparatus comprises a photothermal catalytic reactor, a heating device, an incident light source, a CO2 gas source, a gas chromatograph and a detection system, wherein the gas chromatograph is connected to a hydrogen generator, a low-noise pump and an N2 gas source. The method comprises: opening the CO2 gas source, the N2 gas source, the hydrogen generator, the low-noise pump and the gas chromatograph; weighing catalyst powder,placing the catalyst powder into the sample loading device in the photothermal catalytic reactor, vacuumizing the photothermal catalytic reactor by using a vacuum pump, continuously introducing CO2 gas, and opening the heating device; adding distilled water into the photothermal catalytic reactor; opening the incident light source; sampling at fixed time intervals, wherein the amounts of the samples sampled each time are the same; and immediately making the sample enter the gas chromatograph, testing, and carrying out data analysis by a detection system. With the apparatus and the method of the present invention, the conversion rate of the photocatalytic reaction product can be accurately detected.

Description

technical field [0001] The invention relates to a photothermocatalytic CO 2 A reactor, especially relates to an efficient and accurate method for detecting the yield of photocatalytic products. Background technique [0002] Existing CO 2 The photocatalytic gas reaction device is carried out in a closed container. The advantage of this closed device is that it enables the CO 2 A full reaction was obtained, but the overall material of the device is 304 stainless steel, the heat conduction is too fast, and the thermometer cannot accurately measure the real internal reaction temperature of the catalytic device, which will lead to large experimental errors. The bottle body is completely sealed, and it cannot be sampled or injected with distilled water at any time after assembly. The sample to be tested is directly put into the reactor, the bottom area of ​​the reactor is large, the catalyst is dispersed unevenly, and a part of the sample to be tested will be contaminated on t...
