PCX50A Discover multi-channel parallel photocatalytic reaction system

Introduction:

PCX50A Discover Multichannel photocatalytic reaction device is parked parallel Philae Department of Chemistry,  Light Institute of Catalysis and other experts together with the existing Photocatalytic extensive in-depth analysis, and communication to explore improved after numerous trial after the launch of a major product innovation. The product with the structure, use all the existing design ideas photocatalytic instrument are different. It appears, it will be able to solve a lot of research in photocatalytic real problem:

Feature

1 Efficiency

As we all know, photocatalysis and photoelectric testing different (solar cell), generally have a longer reaction time, especially in some of the catalyst life test, up to hundreds of hours or even several days. PCX50A Discover simultaneous parallel testing nine samples can maximize the elimination of systematic errors such as: radiation attenuation, so that the photocatalytic efficiency of research into a new stage.

2 Extensive use

Since Medallions reactor can be personalized configuration and replacement, thus PCX50A Discover applicable to photocatalytic research work in different directions, to become the pre-test means many professional research and testing before the data. E.g:

• degradation of pollutants instead of traditional photochemical reaction apparatus (Tsinghua University has done methyl orange degradation test, good feedback)

• photocatalytic energy, test synthesis direction (Fuzhou University has to do more comparative sample parallel experiments, good feedback)

• with the known catalysts (such as P25) were the same platform, the same efficiency comparison test conditions in order to obtain a number of performance comparison results of the new catalyst: such as speed of response, quantum yields, differences in life expectancy. In particular, in the study, some abnormal phenomena data can easily be tested by PCX50A Discover, analyze abnormal reasons.

3 Scalability

• Multiple wavelength LED choice, poise Philae will provide more and more selectively;

• You can customize and personalize experiments related to reactor;

4 Economy

• Use of LED, can significantly reduce the cost of research time and cost consuming process, so fewer personnel, funding instability, inadequate laboratories Photocatalytic ongoing.

Technical Parameters:

 Photocatalytic Degradation of Pollutants

In P25 degradation of methylene blue (MB) as an example, photocatalytic degradation of pollutants implementation process.

Reaction conditions: catalyst (the P25) and contaminants (MB of) a magnetically stirred suspension of mixing apparatus, LED light source in the reaction.

Sampling method: the reaction from the liquid sample needle acupuncture treatment cap PTFE pads absorb liquid sample 500μl, microporous membrane, the supernatant was transferred to a pipette, diluted test (using an ultraviolet-visible spectroscopy or other methods of measurement) .

2.2 Photocatalytic water splitting

In Pt / P25 in aqueous methanol photocatalytic hydrogen production, for example, photocatalytic water splitting implementation process.

Reaction conditions: under the action of an aqueous solution of catalyst (Pt / P25) in methanol and the suspension was stirred magnetically mixing apparatus, LED light source in the reaction.

The amount of catalyst: as needed, usually 1: 1000; solution volume: 25 ~ 30ml;

Sampling method: gas sampling needle sampling, sample volume (0.2mL), was transferred to a GC in testing, according to chromatographic curve, can be measured by the absolute amount of the target gas sample gas (mol) take. According to the sample gas volume and the reaction flask spare volume (mL), calculate the target amount of gas generated in the gas phase.

2.3 photocatalytic reduction of CO2

In Cu / TiO2 photocatalytic reduction of CO2, for example, photocatalytic reduction of CO2 implementation process.

Reaction conditions: catalyst (Cu / TiO2) placed in an aqueous solution, under the influence of a magnetic suspension stirring device, stir, using special equipment to multiple Ar system replacement, spare the air within the volume off, and then pass into the system into CO2, under the LED light source reaction.

Sampling method: gas sampling probe with a valve cap from the reaction of tetrafluoroethylene pad acupuncture treatment draw the gas sample 200μl, the valve is closed and transferred to a gas chromatograph to detect. The gas volume and the volume of the reaction flask spare drawn, calculated amount of gas generated product.

Liquid sampling needle cap from the reaction of tetrafluoroethylene pad acupuncture treatment absorb liquid sample 200μl, microporous membrane, the supernatant was transferred to a pipette, take 1μl into the liquid to create the amount of product measured by gas chromatography.
