About

The photoreactor from the IPC PAS consists of a glass vessel with threaded neck, placed inside a metal housing that provides isolation from external light and facilitates the removal of any heat that may be released. The design of the set ensures linearity of the light source relative to the reactor and control over the immersion of the optical fiber inside the reaction mixture.

The photoreactor was designed by dr. Dariusz Lomot thanks to his experience in prof. dr. Juan Carlos Colmenares's group at the IPC PAS https://photo-catalysis.org and thanks to manufacturing support by Mechanical Laboratory of the IPC PAS.

This reactor can be used for chemical reactions in gas, liquid, suspension and on films.

• The set can be equipped with up to 4 LED illuminators with different wavelengths

• The optical fiber with centering tube can be inserted into the protecting glass tube
• The light intensity is controlled using software installed on the computer
• Nozzles allow to supply flowing gas above liquid
• Sealed gas connectors can be attached and top of the reactor covered with a liner
• Reagents are mixed with a magnetic stirrer
• Taking a sample for analysis of liquid phase is possible by syringe with dedicated polyethylene needle

Application

• The proper connectors ensure tightness even for hydrogen generation
• Photocatalytic test reaction in batch system with possible analysis of gas phase above liquid, suspension or films
• Dedicated holder for solid tile with film can be used
• The set is designed for use in scientific laboratories and educational institutions

Testing

The solution was tested in hydrogen generation by photoreforming of methanol.
