Emerging low-carbon technology based on plasma catalysis

Abstract

With the increasing demand for renewable energy, research on plasma catalysis has been gaining momentum as an emerging low-carbon technology. An advantage of nonthermal plasma is that it facilitates large-scale nonequilibrium catalytic reactions that are inaccessible through conventional thermal approaches. Electrical energy activates stable molecules, paving the way for low-temperature chemical reactions in energy-intensive, heat-dependent systems. This article introduces a new concept of plasma-driven nonequilibrium catalysis and describes our research efforts to elucidate the plasma-surface interaction mechanisms, aiming for effective CO₂ recycling toward a low-carbon society.
