Title: Tosiharu Kondo: Innovator in Ceramic Catalyst Technology
Introduction
Tosiharu Kondo is a notable inventor based in Toyoake, Japan. He has made significant contributions to the field of ceramic technology, particularly in the development of high-performance ceramic catalyst bodies. With a total of 7 patents to his name, Kondo's work has had a substantial impact on the industry.
Latest Patents
Kondo's latest patents include innovations in ceramic bodies and catalyst bodies. The ceramic body invention focuses on supporting a required amount of catalyst component without compromising strength. This is achieved by manufacturing the ceramic body without forming a coating layer, resulting in a high-performance ceramic catalyst body that excels in practical utility and durability. The ceramic body is created by substituting elements of cordierite, such as aluminum, with tungsten, which has an empty orbit in d or f orbit. This substitution enhances bonding strength and reduces deterioration, as the catalyst component, platinum, is supported through chemical bonding.
The catalyst body invention aims to provide a solution that exhibits lower degradation due to thermal durability. It maintains higher catalyst performance over extended periods. In this innovation, catalyst components like platinum are directly supported by zirconium and tungsten, replacing elements within the support, such as aluminum in cordierite. The selection of the catalyst component and the supporting element is optimized through simulations, ensuring that the support strength exceeds 5 eV. This approach effectively suppresses the coarsening of catalyst particles, resulting in a high-performance catalyst body with excellent thermal durability.
