Abstract

The escalating impacts of fossil fuel combustion on climate change and air quality have intensified the urgency for cleaner energy conversion technologies. At the same time, increasingly stringent environmental regulations are posing major challenges to conventional combustion and emission control systems. Plasma discharge, with its unique capability to activate molecules and tailor reaction pathways, offers a promising strategy for reducing pollutant emissions. This review systematically explores two key areas: the suppression of soot formation through plasma-assisted combustion, and the removal of soot via plasma-catalysis. Particular emphasis is placed on the synergistic interactions between plasma and catalysts, which enable enhanced reactivity, selectivity, and energy efficiency in pollutant abatement. To fully unlock the potential of plasma-based technologies, future research should focus on developing integrated optimization frameworks that combine plasma operating conditions with tailored catalyst properties, supported by multi-scale investigations to elucidate fundamental reaction mechanisms. These advances will pave the way for plasma-assisted technologies to become a central pillar in sustainable and low-carbon industrial energy systems.
