With a portfolio of 12 patents to his name, Kato's inventions are at the forefront of technological advancements, particularly in applications involving catalysts and adsorbents.
Latest Patents
One of Kato's latest patents focuses on a porous material composed of layered silica and metal oxide. This groundbreaking material consists of SiO4 tetrahedral sheets featuring interlayer bridges of SiO2, which create pores with diameters of 10 Å or more. The material exhibits properties of a solid acid formed by the isomorphous substitution of metal atoms for silicon in the SiO4 frameworks. The innovative production process involves the introduction of organic substances into the interlayer spaces of layered silicates, enhancing the spacing between the crystal layers and forming SiO2 bridges. Following this, intercalated compounds are treated with metal salts for linkage to the SiO4 frameworks, culminating in firing. Remarkably, this porous material can withstand temperatures of 800°C and features pore diameters larger than conventional zeolites, enabling its application as an adsorbent or catalyst, particularly beneficial for high molecular weight molecules, including those involved in petroleum catalytic cracking.
