  • Fundamental Study of Carbon Dioxide Reduction Reaction with Plasma Catalysis

説明

 Carbon dioxide reduction is one of the key technologies for achieving a sustainable society. In this study, plasma catalysis were used to hydrogenate carbon dioxide to produce methane. Plasma catalysis have attracted attention in recent years as a technology promoting a reaction at lower temperatures by various synergistic effects between plasma and catalysts. In this study, molecular sieve with a pore diameter of 3 Å was used as a catalyst and its role was investigated. The results showed that: 1. molecular and atomic adsorption functions of molecular sieves are useful to inhibit reverse reactions; 2. the influence of molecular sieves becomes stronger at higher pressures, resulting in higher methane production; 3. energetic reactive particles derived from hydrogen deactivate molecular sieves; 4. molecules adsorbed on molecular sieve can be recycled by hydrogen plasma irradiation.
