The PCT-LTP-DBD is a modular experimental platform developed for low-temperature plasma science and plasma catalysisresearch, flexibly configurable with DBD discharge, packed-bed discharge, gas-liquid interfacial discharge and other plasma catalytic reaction units. The platform adopts a modular design supporting rapid integration of reactors, power supplies, gas handling and online analysis systems, and can be coupled with in situ/online characterization techniques for simultaneous studies of reaction performance and mechanism. It is widely applicable to CO₂ utilization, methane conversion, ammonia synthesis, water treatment, materials modification and related fields, providing a unified and flexible experimental platform for fundamental research, technology development and pilot validation.

• Modular integration: reactor, power supply, gas handling and analysis modules can be flexibly combined per researchneeds.
• Multi-mode discharge: supports DBD, packed-bed and gas-liquid interfacial plasma reaction systems.
  Characterization coupling: interfaces with online analysis and in situ characterization for simultaneous performance evaluation and mechanism research.
