CEL-PAEM-D8PLUS photocatalytic activity evaluation system (professional automatic carbon dioxide reduction CO2+ fully hydrolyzed water H2O) is a major upgrade of the evaluation of photocatalyst, mainly used for professional automatic carbon dioxide reduction closed system analysis, compatible with photolyzed water and fully hydrolyzed water. The advantage of the system is the new appearance design, more convenient to use, all the pipelines of the system are all temperature control, sample collection and sample analysis to achieve seamless connection. D8plus integrates the glass system into the closed shading box, which is easy to move and not easy to damage. The application of photocatalysis CO2 is more favorable in experiments with more expensive catalysts. Realize online automatic unattended test and analysis; Can choose manual, semi-automatic, automatic sampling mode; Configuration software USB reverse control; The test range is wide, hydrogen, oxygen, CO2, methane, CO, hydrocarbon, formaldehyde, methanol, formic acid and other trace gases.

Functional features and applications:

1) Automatic analysis of carbon dioxide reduction performance of catalyst

2) Activity evaluation of semiconductor materials (TiO2, C3N4, CdS, etc.) catalysts

3) Performance analysis of hydrogen production, oxygen production and total hydrolyzing of the catalyst

4) Trace reaction system, very low amount of catalyst;

5) Special experimental requirements such as photoelectric reaction, gas-solid reaction and membrane catalysis can be configured;

6) Closed integrated design, the panel adopts translucent plexiglass plate, all the closed plate can be removed at any time for easy maintenance;

7) Online automatic unattended test and analysis;

8) Manual and automatic sampling method can be selected (temperature control 200℃);

9) Easy and fast installation, compatible with any manufacturer of gas chromatograph;

10) Wide test range, hydrogen, oxygen, CO2, methane, CO, formaldehyde and other trace gases;
