Outline of Final Research Achievements |
We have developed a method for chemical reactions and material preparation using plasma discharges at the fluid/liquid interface under atmospheric pressure to high pressure, and constructed a flow process that can efficiently utilize plasma at the gas-liquid interface. Using liquid surface discharge plasma in a batch reactor, various chemical reactions and nano-material preparation were carried out, and plasma measurements were performed under high pressure, and radicals and reactive species were measured in the gas and liquid phases. The nanoparticles produced were characterized. A tube-type reactor was fabricated for the distribution process. Slug flow was used as the gas-liquid flow system. Dye decomposition reactions and metal nanoparticle formation were performed, and the effect of pressure was investigated. The relationship between the amount of energy given and the reaction was discussed in relation to the pressure dependence.
