抄録

It is necessary to establish carbon recycling technology toward the realization of carbon neutrality. In our laboratory, we have focused on the decomposition and reduction ability of atmospheric pressure plasma and have been developing plasma devices for CO₂ decomposition and reduction. Results so far has reported particles containing carbon are deposited on the electrode surface inside the reactor after treating CO₂ with atmospheric pressure plasma. The purpose of this journal is to investigate the generation behavior of plasma jets and to analyze the generated carbon-containing particles by CO₂ plasma jets. A metal plate was irradiated with this CO₂ plasma jet, and the surface of the metal plate was observed and analyzed by SEM-EDX. As a result, trace amounts of carbon-containing particles have been confirmed on the surface of the metal plate. In other words, we have succeeded in producing carbon-containing particles outside of the reactor.
