CO Generation from CO2 Using an Atmospheric Microwave Plasma Process

Year: 2025

Type: article

Abstract: With rising CO₂ levels and climate change, finding alternatives to fossil fuels is essential. One attractive option is converting CO₂ into CO and O₂ via an atmospheric microwave plasma process. This study evaluates conversion and energy efficiency by increasing microwave power and CO₂ flow. Power and CO₂ flow were varied, with conversion measured using Fourier transform‐infrared spectroscopy, mass spectrometry, and gas analysis. A maximum conversion of 21.1 % was achieved at a specific energy input of 1.1 eV molecule−1, highlighting the potential of this approach for efficient CO₂ utilization.
