报告摘要:
To build a sustainable society, new innovative materials are needed. Nanoscale structure control of materials can lead to such creations. Ultrafine metal clusters with a few to dozens of metal atoms have unique electronic/geometric structures and properties different from bulk metals of the same elements. Doping different elements into these clusters creates diverse structures, properties, and functions, making them potential units for innovative materials.
To understand and apply metal clusters, it's essential to control their chemical composition and geometric structure. We have developed techniques for this control and a method to control supported metal clusters to enhance the functionality of water-splitting photocatalysts, fuel cell electrocatalysts, and automotive exhaust gas purifying catalysts.
We have achieved the highest water-splitting activity for UV-responsive BaLa4Ti4O15 photocatalysts, created platinum electrocatalysts with better oxygen-reduction activity than current fuel cell ones, and developed highly functional automotive exhaust gas purification catalysts. Our research uniquely achieves atomic-level control of metal clusters from synthesis to support control. This presentation summarizes our recent related work.
