Introduction
A photocatalytic reactor is a laboratory instrument used to carry out photocatalytic reactions, in which a photocatalyst, such as titanium dioxide, is activated by light, typically ultraviolet or visible light, to drive chemical reactions, and it is used in research on photocatalysis, environmental remediation, water treatment, and green chemistry. The reactor consists of a reaction vessel, a light source, such as a mercury lamp, xenon lamp, or LED, that illuminates the reaction mixture, and, in many designs, a cooling system, a magnetic stirrer, and a gas supply for purging or for reactive gases; in operation, the reactant solution and the photocatalyst are placed in the vessel, the light source is turned on, and the photocatalyst absorbs the light and generates reactive species, such as hydroxyl radicals, that oxidize or reduce the reactants, and the reaction is monitored by sampling and analysis, and the reactor allows the control of the light wavelength and intensity, the temperature, and the reaction time. Photocatalytic reactors are used for studying the degradation of organic pollutants in water and air, for research on the production of hydrogen by water splitting, for the synthesis of chemicals, for the reduction of carbon dioxide, for the disinfection of water, for studying the mechanisms of photocatalysis, for testing photocatalyst materials, and for many other applications, in environmental science, chemistry, materials science, and energy research, and they are available in various configurations, from simple batch reactors to flow reactors, with features such as controlled illumination, temperature control, and sampling ports. With their controlled photocatalytic reactions, photocatalytic reactors are essential instruments for photocatalysis research.

FAQ
Q1: What testing scenarios is this reactor mainly applied to?
A: The photocatalytic reactor is used in chemistry research, environmental engineering, materials science, energy research, chemical engineering and research to study photocatalytic reactions under controlled UV/visible light irradiation for photocatalytic degradation of pollutants, water splitting (hydrogen production), CO2 reduction, organic synthesis and photocatalyst characterization. It supports photocatalytic degradation of organic pollutants (dyes, pharmaceuticals, pesticides) in water, photocatalytic water splitting for hydrogen production, photocatalytic CO2 reduction to fuels, photocatalytic organic synthesis (oxidation, reduction), photocatalyst material characterization and optimization, solar energy conversion research, and environmental remediation technology development. The controlled light source and reaction conditions enable systematic study of photocatalytic mechanisms, kinetics and catalyst performance.
Q2: What standards does the reactor comply with?
A: The photocatalytic reactor follows relevant ISO, ASTM and GB/T standards for photocatalytic testing, including ISO 10678 for photocatalytic activity of surfaces, ISO 22197 for photocatalytic materials, ASTM standards for photocatalysis, and relevant research standards. The hardware complies with IEC 61010 laboratory safety standards and UV radiation safety standards (IEC 60825, GB 7247). Calibration should use certified reference materials (e.g., methylene blue, phenol) and calibrated light meters. UV safety follows applicable regulations.
Q3: What is the warranty period for the whole reactor and key components?
A: The whole photocatalytic reactor is covered by a 12-month warranty. The reactor vessel, light source, filter, cooling system, controller and housing are covered, while lamps, filters, seals and fuses are consumables or accessories. Damage from improper use, lamp breakage or unauthorized repair is excluded. Extended service contracts may be available.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained research personnel familiar with photocatalysis, photochemistry and chemical safety. We provide operation manuals, training and application support. Proper catalyst preparation, reaction setup, light source selection, filter use, temperature control, sampling, safety procedures (UV radiation, chemicals) and data interpretation are important for safe, effective photocatalysis research.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Light intensity calibration with a calibrated light meter recommended every 6-12 months or per lamp hours. Lamp output and spectrum verified periodically. Temperature control calibration. Lamp replacement per usage hours. Full system performance verification annually with reference reactions. Routine cleaning of reactor and lamp.
Q7: Are supporting consumables universal?
A: Lamps (UV, visible), filters, seals, reference materials and cleaning supplies are available from laboratory suppliers, though lamp type should match the instrument. Long-term consumable cost depends on usage and lamp replacement frequency.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes reactor type (batch, flow, annular), capacity, light source (UV mercury, xenon, LED, solar simulator), wavelength/filter selection, temperature control, stirring, gas supply (oxygen, nitrogen, CO2), sampling system, data output and accessories. Additional lamps, filters and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Yes, photocatalytic reactors include on-site installation, commissioning, calibration and operator training by certified specialists. Site preparation guidance is provided before delivery, including UV safety shielding requirements.
Q10: What types of samples are compatible with this equipment?
A: The photocatalytic reactor studies photocatalytic reactions of liquid, gas and solid samples including aqueous pollutant solutions, water (for splitting), CO2 gas, organic reactants and photocatalyst materials within the reactor capacity, light source and specification. Different photocatalytic reactions require specific conditions: aqueous degradation (catalyst suspension, oxygen or air), water splitting (sacrificial agent, inert gas), CO2 reduction (water vapor, CO2 gas), organic synthesis (specific reactants, solvent). Users should select appropriate light source and wavelength for the photocatalyst (UV for TiO2, visible for doped/sensitized catalysts), use proper filters to select wavelength range, control temperature (exothermic/endothermic reactions), use appropriate gas atmosphere (oxygen for oxidation, inert for reduction), calibrate light intensity with a calibrated meter, include appropriate controls (dark control, no-catalyst control, no-light control), follow proper sampling and analysis methods (UV-Vis, HPLC, GC, TOC), report results with reaction conditions (catalyst loading, light intensity, wavelength, temperature, pH, time) specified, and for photocatalyst comparison, use standardized test conditions (e.g., ISO 10678 for methylene blue degradation). The reactor should be operated with proper UV safety shielding (never expose eyes/skin to UV). The lamp should be allowed proper warm-up time. The reactor should be cleaned thoroughly between experiments to prevent catalyst carryover. For suspension systems, use proper stirring to maintain catalyst suspension. For gas-phase reactions, use proper gas flow control and sealing. The photocatalyst should be properly characterized (XRD, BET, UV-Vis DRS) alongside photocatalytic activity testing. Waste should be disposed of per applicable chemical waste regulations. The light source should be replaced when output degrades. For solar energy research, use a solar simulator (AM 1.5G) for standardized testing.
