About this collection
Non-thermal plasma is an emerging technology for sustainable chemical production, aiding in the electrification of industrial processes particularly those powered by renewable energy sources. Its benefits include rapid on/off switching and a small footprint. Coupling it with catalysis offers greater control over reaction pathways and modulation but controlling specific conversion paths remains challenging due to their complexity. Consequently, the technology is still far from reaching research maturity. Despite progress, understanding the interaction mechanisms between plasma and catalysts, crucial for upscaling, is still not fully understood. This special collection focuses on recent advances in the development of plasma technologies to integrate into energy intensive industries to achieve the ambitious target of zero emissions in the view of a circular carbon economy.
