Outline of Final Research Achievements

We developed various types of gel catalyst such as copolymer gels bearing a sulfo group (acid catalyst), metal nanoparticle-loaded gels, and biocatalyst-loaded gels. The adsorption or absorption of reactants onto gel catalysts can enhance the apparent rate of the reaction occurring within the gel. The performance and feasibility of gel catalysts were demonstrated for following reaction systems useful in the chemical industry, environment, and bioenergy fields; the Suzuki-Miyaura cross-coupling reaction catalyzed by Pd nanoparticle-loaded gels; arsenic adsorption and sensing by zirconia nanoparticle-loaded hydrogels; the ethanol fermentation catalyzed by yeast cell-immobilized macroporous monolithic hydrogels; the biodiesel fuel production catalyzed by copolymer gels bearing a sulfo group.

Academic Significance and Societal Importance of the Research Achievements

特異的な溶媒吸収能や物質吸着能、および活性部位の有効な保持能を持つ機能性ゲル触媒の創製、機能発現のメカニズムの解明と体系化、およびゲル触媒の高機能化と設計指針に関する学術基盤の構築を達成した点に学術的意義がある。また、機能性ゲル触媒のコンセプト自体が、文献等で前例がない独自のものである。ゲル酸触媒を用いたバイオディーゼル燃料製造、金属ナノ粒子担持ゲルを用いた有機合成反応、酵母固定化多孔質ゲルを用いたエタノール発酵、など、開発した機能性ゲル触媒を社会的に有用な反応系に応用した点に社会的意義がある。
