Developed by Beijing Perfectlight Technology Co., Ltd., the PLR MSCRD-I Multi-Field Synergistic Catalytic Organic Pollutant Degradation System is an integrated liquid–solid catalytic research platform that combines optical, electrical, thermal and magnetic field control.
Each physical field can be operated independently or combined with other fields according to experimental requirements. The system also integrates continuous-flow gas and liquid delivery, product post-treatment, operating parameter acquisition and multiple safety protection functions. It is suitable for catalyst screening, catalytic performance evaluation, reaction parameter optimization and multi-field coupling mechanism studies.
The system is equipped with a PLS 300 W xenon lamp, which can provide simulated sunlight or selected wavelength bands according to experimental requirements. Light is precisely introduced into the reaction zone through a quartz light guide, exciting the catalyst to generate electron–hole pairs and reactive species for the oxidative degradation and mineralization of organic pollutants.
The electrolysis system can apply a voltage of 0–30 V and a current of 0–10 A to the electrodes, with constant-voltage and constant-current operating modes available. It enables researchers to investigate the effects of an applied electrical field on pollutant degradation efficiency and reaction pathways through direct electrochemical oxidation or the generation of reactive intermediates.
The temperature control system adopts PID regulation, providing a temperature range from ambient temperature to 100°C with a control accuracy of ±1°C. By adjusting the reaction temperature, the system supports studies of catalytic reaction kinetics, thermal activation and synergistic photothermal or electrothermal effects.
The magnetic field system consists of six N52 high-strength permanent magnets, DT4 pure iron magnetic flux-guiding plates, a high-precision linear guide and a stepper motor. The linear stage provides a travel range of 150 mm and a positioning accuracy of 0.1 mm. By adjusting the distance between the magnets, the magnetic field intensity in the reaction zone can be varied to investigate its effects on electron transfer, electron spin and catalytic reaction pathways.
Four physical fields are integrated into a single experimental platform and can be operated independently or in any required combination. This design helps reduce interface incompatibility and experimental reproducibility issues associated with assembling multiple separate instruments.
The system supports 50×50 mm and 100×100 mm electrolytic cells, allowing users to select the appropriate configuration according to catalyst quantity and experimental scale. The reactor incorporates titanium alloy end plates, PEEK flow-channel plates and quartz optical windows for excellent corrosion resistance.
The gas delivery system uses a mass flow controller and back-pressure valve to regulate gas flow and system pressure accurately. The liquid delivery system incorporates a gear pump, Y-strainer and check valve to provide continuous and stable liquid delivery, supporting long-term steady-state experiments and kinetic data acquisition.
The system adopts a PLC and HMI control architecture and is equipped with a 10-inch color touchscreen. More than ten operating parameters, including temperature, pressure, flow rate, voltage and current, can be centrally configured and displayed. Experimental data can be recorded automatically at predefined intervals and exported as CSV files via a USB drive for subsequent processing with Excel, Origin or Python.
A 200 mL heated bubbler and a gas–liquid separator are provided for effective separation of gaseous and liquid products. Interfaces for online analytical instruments such as GC and MS can be incorporated according to experimental requirements, facilitating the detection of reaction intermediates and final products.
The system is equipped with an emergency stop button, audible and visual alarms, magnetic-stage travel limits, and overpressure, overtemperature, overcurrent and leakage protection. These functions improve operational safety and experimental controllability.
The electrolytic cell dimensions, catalyst mounting method, number of gas channels, gas-mixing configuration, control strategy and online analytical interfaces can be customized to accommodate different reaction systems and research requirements.
