PLR MSCRD-I Photo–Electro–Magneto–Thermal Multi-Field Catalytic System

How can light, electricity, magnetism and heat be controlled independently—or coupled deliberately—inside one catalytic experiment? As catalysis research moves beyond single-variable studies, the challenge is no longer simply adding another function. Researchers need a platform that can build reproducible combinations of external fields, record the complete process and support quantitative comparison.

To address this need, Perfectlight has introduced the PLR MSCRD-I Multi-Field Catalytic Organic-Pollutant Degradation System. The platform integrates photo-, electro-, magneto- and thermal-field control in a single continuous-flow system. Each field can be operated independently or combined with the others, supporting catalyst evaluation, process optimization, mechanistic studies and subsequent scale-up. The system has already been commissioned in a university laboratory.

1. Four Energy Fields on One Experimental Platform

The PLR MSCRD-I brings four controllable energy inputs into the same reaction platform. Researchers can construct single-field control experiments or multi-field combinations without rebuilding the entire setup, helping improve experimental efficiency, repeatability and comparability.

• Photonic field: a xenon lamp provides simulated sunlight. Photons at selected wavelengths excite the catalyst to generate electron–hole pairs and reactive species such as hydroxyl radicals (•OH) and superoxide radicals (•O₂⁻), enabling deep mineralization of organic pollutants.
• Electric field: precisely controlled voltage or current can drive direct electro-oxidation or generate highly oxidative intermediates, broadening the operating window of pollutant degradation.
• Magnetic field: six N52 permanent magnets are installed on a high-precision linear guide with 0.1 mm positioning resolution. Continuous position adjustment changes the magnetic-field intensity and supports quantitative correlation between field conditions and catalytic performance. This makes it possible to investigate spin-dependent electron behavior, reaction pathways, catalyst stability and active-site effects.
• Thermal field: semiconductor/electric heating provides an operating range from room temperature to 100 °C with ±1 °C control accuracy, supporting kinetic acceleration and systematic investigation of thermal contributions.

2. Intelligent Data Acquisition and Traceability

The integrated PLC automatically records more than ten experimental parameters, including pressure, temperature, flow, voltage and current. Data can be exported in standard CSV format, while historical trends and alarm records remain traceable. This supports transparent data management and makes it easier to compare long-running experiments or reproduce a specific operating window.

3. Continuous-Flow Architecture for Steady-State and Kinetic Studies

The system includes independently controlled gas and liquid delivery. A mass-flow controller provides a gas-flow range of 0–300 sccm and pressure control from 0 to 0.5 MPa. A precision liquid pump provides a stable flow of 0–1000 mL/min. Continuous and controlled reagent delivery improves data continuity and comparability, while interfaces can support online analytical instruments such as electrochemical workstations and gas chromatographs.

4. Modular Electrochemical Cells for Different Research Scales

Standard 50 × 50 mm and 100 × 100 mm modular cells support work ranging from milligram-scale catalyst screening to gram-scale performance evaluation; other sizes can be customized. Corrosion-resistant materials—including titanium alloy, PEEK and quartz glass—are combined with a dual-seal design for stable operation under illumination, electrochemical conditions and continuous flow. Different xenon-lamp sources and light-guide configurations can also be integrated for photoelectrochemical testing.

5. High Localization and Expandable Instrument Integration

The platform uses highly localized core components to strengthen supply-chain stability and technical support. According to the original configuration comparison, the integrated design can reduce total equipment cost by more than 40% versus an imported solution assembled from a separate photoelectrochemical workstation, magnetic-field module and temperature-control stage.

Reserved communication interfaces allow future integration with GC, MS and other online analytical instruments, enabling a more automated closed loop from reaction control to product analysis.

Why Multi-Field Control Matters

Catalysis research continues to introduce new experimental variables and more complex coupled mechanisms. A scalable research platform therefore needs flexible condition construction, reliable process recording and an architecture that can evolve with the research program. By combining photoelectrocatalysis with magnetic-field control, continuous flow, modular reactors and synchronized data acquisition, the PLR MSCRD-I provides an extensible foundation for catalyst evaluation and mechanism-oriented research.
