AI Technical Summary
Existing interface designs between plasma catalytic reactors and molecular beam mass spectrometry suffer from liquid reactant blockage, making it difficult to achieve high-quality resolution and high-time-resolution online monitoring of gas-liquid phase reactants under plasma catalytic conditions.
A microsyringe was used to control the flow rate of liquid-phase reactants, and a mass flow meter was used to control the flow rate of gas-phase reactants. Combined with an RF-driven discharge device, components such as a quartz tube, an inner quartz tube, copper wire, and a ring-shaped iron wire mesh were designed to construct a molecular beam mass spectrometry detection device for plasma catalytic components of gas-liquid phase reactants.
High-quality and high-time-resolution online monitoring of gaseous and liquid reactants under plasma catalytic reaction conditions was successfully achieved, avoiding blockage of liquid reactants and improving the stability of the reaction system and the ease of experimental operation.
