Outline of Research at the Start

本研究では、種々の希土類金属および遷移金属を担持した新規不均一系酸化触媒を開発し、温和な条件における環境残留性の高いパーフルオロアルキル化合物の高効率な酸化的分解反応を行う。さらに、本反応系に別の有機基質を共存させ、有機基質への酸化的なフッ素導入反応を同時に行うタンデム型の触媒的酸化反応系を見出す。これにより、パーフルオロアルキル化合物をフッ素源とする有機基質のフッ素化反応系を構築し、酸化的フッ素転移反応の創出を目指す。

Outline of Final Research Achievements

SiO2 supported by sequential impregnation of palladium and cerium oxides was prepared as a catalyst. TEM measurements showed that a core-shell structure with Pd as the nucleus and CeOx as the shell was formed on the SiO2. In the presence of persulfate, BF4 ion was produced from B(OH)3 in the oxidative degradation of PFOA alternative substrate, and F ion was produced by the decomposition. In addition, catalytic oxidation of pentafluorophenylsulfonate was carried out using hydrogen peroxide as an sacrificial oxidant, and the conversion yields and the yields of fluorinated compounds were determined. As a result, except for cerium, it was found that the substrate conversion yields and the yields of tetrafluoroborate ion tended to improve as the elemental number of the added rare earth increased.

Academic Significance and Societal Importance of the Research Achievements

パーフルオロアルキルスルホン酸(PFAS)等は、その安定性に基づき、環境中で分解を受けずに半永久的に堆積する。PFASは通例の分解処理法では厳しい条件を必要とし、分解が進行しても有害なフッ化物イオンが生成し、環境・人体に対して依然として重篤な悪影響をもたらしうる。そこで希土類金属や貴金属の特異な反応性を利用することで、より温和な条件で分解することが可能になり、また生成するフッ化物イオンを他の化合物に付加させることで、有害物から有価物への変換をワンポットで行うことができる。セリウムは希土類元素の中でも安価なため、大スケール反応への展開も見据えることが可能である。
