LED Blue Light Catalytic Reactor

Product advantagessex

*Visible light catalysis research is different from photoelectric testing (such as solar cells), usually requiring a longer reaction process, especially for some catalyst lifespan tests, which can reach hundreds of hours or even tens of days. SynLED-16 A Discover can simultaneously test 16 samples in parallel, effectively eliminating systematic errors such as radiation attenuation changes to the greatest extent possible, bringing the efficiency of photocatalytic research to a new stage.

Widely applicable

Due to the personalized configuration and replacement of both the lamp panel and reactor, synLED-16 A Discover can be applied to photocatalytic research work in different directions and can become a pre testing method for many professional research and testing data. For example:

·Replacing traditional photochemical reactors for pollutant degradation

·Testing of photocatalytic energy and synthesis direction (parallel comparative experiments with multiple samples have been conducted by universities such as North Carolina, Peking University, and Nanjing University in the United States, and feedback has been positive)

·Drug modification: Traditional Western medicine generally has certain drug resistance, and how to develop new structural drug molecules is a major challenge in new drug development. The use of this device can quickly establish a batch of drug molecules and intermediates with * structure, greatly improving the efficiency of new drug development.

·Small scale drug synthesis trials (parallel comparative experiments with multiple samples have been conducted at universities such as North Carolina, Peking University, and Nanjing University in the United States, with good feedback)

·Fine chemical production and research and development

scalability

·Multiple wavelength LEDs are available for selection, and Blue New Technology will provide more and more options;

·Can customize reactors related to personalized experiments;

economy

The use of LEDs can significantly reduce research time and process consumption costs, enabling laboratories with limited personnel, unstable funding, and insufficient resources to continue conducting visible light catalytic research.

3. Application scope

Photocatalytic degradation of pollutants

Taking the degradation of methylene blue (MB) by P25 as an example, the process of photocatalytic degradation of pollutants is achieved.

Reaction conditions: The catalyst (P25) and pollutant (MB) are mixed evenly under the action of a magnetic suspension stirring device, and the reaction can be carried out under the illumination of an LED light source.

Sampling method: The liquid sampling needle draws 500 μ l of liquid sample from the PTFE pad on the reaction bottle cap, uses a microporous membrane, transfers the clear liquid to a pipette, dilutes it, and tests it (using UV visible spectroscopy or other measurement methods).

Photocatalytic decomposition of water for hydrogen production

Taking Pt/P25 photocatalytic hydrogen production in methanol aqueous solution as an example, the process of photocatalytic water splitting for hydrogen production is achieved.

Reaction conditions: The catalyst (Pt/P25) and methanol aqueous solution are mixed uniformly under the action of a magnetic suspension stirring device, and the reaction can be carried out under the illumination of an LED light source.

Catalyst dosage: usually 1:1000 as needed; Solution volume: 25-30ml;

Sampling method: Use a gas sampling needle to sample, with a volume of 0.2mL, and transfer it to gas chromatography for detection. Based on the chromatographic working curve, the content of the target gas in the gas sample can be measured (mol). The target gas generation amount in the gas phase can be calculated based on the sampled gas volume and the empty volume (mL) of the reaction bottle.

Visible photochemical synthesis

Suitable for various types of visible light catalysis research:

·Visible light catalytic oxidation reaction

·Visible light catalytic reduction reaction

·Visible light catalyzed neutral reaction.

Reaction conditions: Catalysts (ruthenium, iridium complexes, organic dyes, etc.) and raw materials are mixed uniformly under the action of a magnetic suspension stirring device, and then reacted under the illumination of an LED light source.

Sampling method: The liquid sampling needle draws 200 μ l of liquid sample from the PTFE pad on the reaction bottle cap, uses a microporous membrane, transfers the clear liquid to a pipette, and takes 1 μ l for gas chromatography measurement. Or use TLC spot plate testing.

6. Instrument usage and precautions

SynLED-16 A Discover Instructions:

Place synLED-16 A Discover on a suitable magnetic stirrer, plug the instrument plug into the power supply~220V, the blue LED lights up, and the instrument starts working. After the reaction is complete, unplug the point source plug, the blue LED will turn off, and the instrument will stop working.

Notes:

At all stages of operation, maintenance, and instrumentation, the following basic safety measures must be followed. When using the instrument, it should be operated according to the instructions. Improper use can cause the instrument to work normally and even damage it. When using the instrument, blue light must be worn to protect the eyes and avoid direct eye contact with the LED.

A、 In order to avoid electric shock accidents, the input power cord of the instrument must be grounded. This instrument uses a three core grounding plug, which has a grounding pin. If the plug cannot be inserted into the socket, an electrician should install the correct socket to prevent the instrument from losing its grounding protection function.

B、 Pay attention to the use of power supply:

Before connecting to the AC power supply, ensure that the voltage is consistent with the voltage required by the instrument (with a tolerance of ± 10%), and ensure that the rated load of the power socket is not less than the instrument requirements.

C、 Pay attention to using power cords:

This instrument usually uses the power cord that comes with it. If the power cord is damaged, it must be replaced and cannot be repaired. When replacing, a power cord of the same type and specification must be used instead. No objects are allowed to be placed on the power cord when using this instrument. Do not place the power cord in areas where personnel are walking.

D、 Pay attention to the placement of the instrument:

This instrument should be placed in a cool, ventilated, dry, and dust-proof location. For better heat dissipation, the instrument should be kept at an effective distance (N>30cm) from other objects in a ventilated area.

E、 Avoid strong acids and bases.

We believe that synLED-16 A Discover is an open platform with a basic systematic architecture. According to the research direction, it is a constructible and flexible system, and many functional and specific components, as well as new research capabilities, cannot be fully developed in a short period of time. We are very willing to discuss and develop applicability issues with every user regarding research needs. Through joint efforts with researchers, we continuously expand and improve the research capabilities of synLED-16 A Discover to meet the professional needs of users.
