Outline of Final Research Achievements |
Observation of a change of catalytic properties by magnetic transition was tried in order to reveal a relationship between a valence electron spin and catalytic properties. Mainly, Ni based alloys were employed as catalysts in a ribbon form for oxidation of CO, hydrogenation of hydrocarbons and so on. However, the change of catalytic properties by magnetic transition was not observed. This was attributed to deterioration of catalysts with time. Hence, I built a catalytic measurement system which can analyze with high speed and high accuracy, and employed a noble metal based catalyst which is hard to be deteriorated with time. In CO oxidation with a Pd85Co15 powder catalyst, it showed a catalytic property change considered to be due to magnetic transition. I will reveal a relation to a spin polarized valence electronic structure in future.
