From a photocatalytic perspective, considering gas-solid phase photothermal coupled reactions, the parameters can reach 550°C and 1.6 MPa, which can be used for the research of gas-solid phase photocatalysis/thermal catalysis/photothermal catalytic reactions. Liquid samples can be added at initial room temperature conditions or for humidification during the reaction.
With a focus on continuous differential reaction and considering closed integral reaction needs, this aims to provide a controllable flow and pressure, as well as light/heat-coupled reaction testing platform that can be used in conjunction with our company's Xenon Lamp Light Source. It is suitable for a wide range of photothermal catalytic reaction systems, such as photothermal CO₂ reduction, photo/thermal ammonia synthesis, and photo/thermal catalytic oxidation, etc.
