| Research Abstract |
Three-dimensionally integrated micro-solution plasma, in which the plasma-liquid nano interfaces are integrated, has been proposed. A proto-type reactor has been manufactured, which has excellent water treatment efficiency. The origins of the high efficiency have been clarified through time-resolved optical emission spectroscopy and plasma chemical reaction simulations. It has been predicted that a nano-scale space-charge layer is formed beneath the liquid surface in contact with plasma, and that semi-preferential reactions can occur between gas-phase species and liquid-phase ions. Er:YAG laser irradiation on water has been investigated as an alternative method for generating plasma-liquid nano interfaces, and proved to be accompanied by sterilization effects.
