项目摘要

エネルギー変換反応において多電子移動反応は重要な役割を果たすことが知られているが、一方でその反応機構に対する理解の不足が高活性な触媒の開発を妨げている。そこで本研究では電気化学測定と分光測定を同時に測定することにより多電子移動反応の反応機構の検討を行った。具体的にはシリコンプリズムや金の表面を多電子移動触媒で被覆した電極材料を作成し、反応駆動下の電極触媒に全反射型赤外吸収分光や表面増強ラマン散乱分光などの振動分光を適用する測定手法を開発し、測定を行った。その結果、酸化マンガン表面では酸素発生条件下において水分子の水素結合状態が変化し、水素結合のネットワークを持たない孤立した水分子の割合が増加することを見出した。酸素発生反応生化学的な見地からも注目の高い反応であり、水分子のプロトンネットワークの反応への関与を示す同結果は自然界との比較からも示す興味深い知見であると考えている。また、同触媒上でメタノール酸化を行った場合には塩基性条件下においてのみ触媒表面へのメタノールの吸着が強く生じ、同時に酸化のための過電圧が大幅に減少することを明らかにした。この結果は今後酸性などの他条件下での活性向上に向けて材料設計の指針を与えるものと考えている。電気化学と振動分光を組み合わせた同様な研究は以前から報告されているが、それらのほとんどは単結晶金属の表面を利用したものに限られていた。それに対して、本研究で開発した手法は金属酸化物など多様な触媒に適用可能である。したがって、今後元素戦略上重要な種々の多電子移動触媒の反応機構を解明する上で有用な手法となると考えられる。

It is important to know that you are not responsible for the anti-computer movement, and that one party is aware that you are not fully aware that the highly active catalyst is not available.

The vibration spectrometer is used to determine the performance of the vibration spectrometer. The results showed that under the condition of the growth of acid on the surface of acidified water, the combination of water and water molecules, the combination of water and water, and the combination of water and water molecules were isolated. The chemical reactions of acids and biochemistry are closely related to the high levels of biochemistry, water molecules and water molecules. The results show that the results are the same as those in nature. On the same catalyst, under the basic conditions of the catalyst, the surface of the catalyst is strongly activated, and at the same time, the acidizing effect is much higher than that of the catalyst. The results show that in the future, under the condition of acid temperature, the temperature activity will be higher than that of the control material design. The Electro-Chemical Vibration Spectroscopy (EVS) has been used in the study of previous reports on the use of temperature limits on the surface of crystalline metals by means of thermal analysis. In this study, the use of metal acidates and the use of multi-catalyst is possible. In recent years, there are several kinds of important elements in the future. Multi-computer mobile catalysts have been explained by the anti-government agency that they have used a lot of tricks to test their performance.
