Outline of Final Research Achievements

We have developed novel nanoparticle catalysts covered with hydroxylated fullerene as a protective molecule and a chemical transformation reaction using them. We succeeded in preparing gold, platinum, palladium, and rhodium nanoparticles by solution-phase chemical reduction. It was found that the obtained nanoparticles formed a water-dispersible colloids and exhibited high stability in water. In particular, it was found that gold catalysts and platinum nanocatalysts showed high catalytic activity for the oxidation reaction of organic compounds. We also succeeded in preparing nanoparticles of base metal oxides as well as precious metals.

Academic Significance and Societal Importance of the Research Achievements

通常金属ナノ粒子を調製するためにはナノ粒子同士の凝集を防ぐため、それを保護する化合物を添加する必要があり、一般には高分子や固体担体、配位子などが用いられる。一方で、水酸化フラーレンは弱い配位力をもつ「分子」であるにもかかわらず効果的にナノ粒子を安定化できる分子性サーファクタントとして機能するため学術的に興味深い。また、有用な化学反応を触媒するだけでなく、貴金属ナノ粒子が完全に水に分散するため、インクジェットプリンティングなどを活用した微細配線などへの応用も期待される。
