Outline of Research at the Start

本研究では、高活性+高選択的な低級アルカンの脱水素反応場を構造体触媒システムで創製するために、触媒反応場に直接電気エネルギーを投入して気相分解を回避し、かつ硫化物系触媒の表面格子硫黄種のレドックス機能性を電気的に励起する。硫化物系構造体触媒への直接電気励起は、まだ誰も取り組んでいない新たな反応ルートの開拓であり、物質変換技術に関した新しい学理を切り拓く研究テーマである。

Outline of Final Research Achievements

In the present study, a highly active and highly selective dehydrogenation reaction field was created in a structured catalyst system by directly injecting electrical energy into the catalytic reaction field to avoid gas-phase decomposition. Specifically, it was found that selective heating of the catalyst section by energized heating produced C5 olefins at a high selectivity. The system of energized catalysts was also deployed in the oxidative dehydrogenation of propane and the methanation of CO2. The energized heating system, in which the porous catalyst was directly heated by applying current and voltage to the catalyst, resulted in efficient reactions. Furthermore, it was found that the temperature of the catalyst bed could be easily controlled in the methane conversion reaction of CO2 using the energized catalyst, and that high CO2 conversion rates could be achieved even with a small power supply of a few watts, demonstrating the usefulness of the proposed system.

Academic Significance and Societal Importance of the Research Achievements

本研究における学術的意義は、触媒反応場への直接的な電気エネルギー投入によって高性能な脱水素反応場を実現した点にある。通電加熱を利用することで、従来の気相分解を回避し、特定の化学反応において高効率・高選択率を達成した。これにより、少量の電力で高い反応効率を示す新たな触媒システムの可能性を示した。社会的意義は、再生可能エネルギーの導入が進む現代において、本研究で開発された通電加熱式システムが、低消費電力で高効率な化学反応を可能にする点が挙げられる。特に、CO2のメタン化反応において高いCO2転化率を示すことから、温室効果ガスの削減や再生可能エネルギーの有効利用に貢献する技術として期待される。
