Latest Patents

One of his latest patents focuses on a catalyst for purifying exhaust gas. This invention aims to improve carbon monoxide (CO) conversion in stoichiometry-lean atmospheres while preventing pressure loss. The catalytic coating layer consists of a lower layer that includes an oxygen storage capacity material and an upper layer formed on the surface of the lower layer, which contains a catalytic noble metal. The thickness of the upper layer is designed to be between 5 µm and 40 µm, ensuring optimal gas diffusibility and maximizing the effectiveness of the oxygen storage capacity material.

Another notable patent by Ito is for a ceramic honeycomb structural body and methods for preparing the same. This invention provides a structural body that can effectively support a catalyst while demonstrating superior mechanical strength, even with thinner walls. The structural body comprises lattice walls formed by numerous cells that serve as fluid channels, along with a peripheral wall that encases the lattice walls. The outer peripheral portion of the lattice walls contains a densified area with smaller porosity compared to the inner peripheral portion, enhancing the overall performance of the structure.
