Working Principle:
The Shanghai 3S Technology Multi-Channel Photocatalytic Reactor is a high-efficiency device that utilizes light energy to drive chemical reactions. Its core working principle involves exciting a photocatalyst with a light source to generate electron-hole pairs, which then drive redox reactions. When light of a specific wavelength irradiates the catalyst surface, valence band electrons are excited and transition to the conduction band, forming highly reactive charge carriers. These carriers interact with reactant molecules to initiate redox reactions, achieving chemical transformations.

Key Parameters for Specification Selection:

• Wavelength Range: 250-975 nm, with nearly 100 wavelengths available for selection, customizable for specific wavelengths.

• Light Intensity Performance: Up to 1000 mW/cm², with a light attenuation rate below 5%/year.

• Reaction Scale: Compatible with reaction tubes of 2-50 mL, including specialized containers such as NMR tubes and Schlenk tubes.

• Control System: 10 independent working stations, supporting individual power control, time setting (0-99 hours), and smart temperature control.

Product Features:

• Precise Light Source Control: LED light sources with a lifespan exceeding 20,000 hours, consuming only 30% of the energy of traditional sources.

• High-Efficiency Mass Transfer Design: Microchannel structures enhance heat and mass transfer efficiency by 3-5 times.

• Safety Protection System: Equipped with magnetic stirring, explosion-proof valves, and a circulating water cooling system.

• Modular Design: Integrated light source modules for easy replacement.

Application Scenarios:

• Pharmaceutical Field: Steroid drug synthesis, green synthesis of pharmaceutical intermediates (e.g., Dydrogesterone).

• Environmental Protection Field: Wastewater treatment, VOCs (volatile organic compounds) purification, dye degradation.

• Chemical Industry: Chlorination, bromination, oxidation, and polymerization reactions.

• Materials Science: Preparation of nanomaterials and synthesis of functional glass.
