Currently, the conversion of CO₂ plasma faces challenges such as declining conversion rates under high flow velocities, poor stability, and the difficulty in balancing energy efficiency with processing capacity. This study introduces a magnetic field to the conventional gliding arc (GA) discharge and finds that the magnetically stabilized gliding arc (with the magnetic field oriented along the -x axis) significantly enhances both the CO₂ conversion rate and disturbance resistance. The conversion rate increased by over 40% compared to the traditional GA and by more than 15% compared to the magnetically accelerated gliding arc (with the magnetic field along the +x axis). This research offers a feasible approach to address the issues of stability and scalability in CO₂ conversion, contributing to the industrialization of plasma-assisted carbon conversion technology.
