Reducing the use of catalysts and improving their functionality are important issues in many catalytic reactions that support society. As a way to solve this problem, research on nanoscale catalysts is being conducted all over the world.
In this paper, we succeeded in creating nano-clusters composed of several platinum atoms by size, and carefully investigated the correlation between the structure and catalytic performance of the oxidation reaction of carbon monoxide. As a result, it was found that platinum atoms with a small coordination number located at the edge of the nanocluster have a small activity, and thus an atomic-level structural design that increases the coordination number of these atoms is necessary to maximize the catalytic performance. This knowledge is expected to contribute to the resource-saving design of energy conversion catalyst materials to achieve carbon neutrality.
