Title: Satoshi Nagao: Innovator in Oxygen Storage Materials

Introduction

Satoshi Nagao is a prominent inventor based in Gotenba, Japan. He has made significant contributions to the field of materials science, particularly in the development of oxygen storage materials. With a total of 10 patents to his name, Nagao's work has had a substantial impact on various industries.

Latest Patents

Nagao's latest patents include a production method of oxygen storage material. This method involves adding a hydroxycarboxylic acid to an aqueous solution containing a cerium salt, a zirconium salt, an aluminum salt, and at least one selected from a lanthanum salt, a magnesium salt, and a calcium salt to produce a gel. The gel is then heated to obtain a solid product through the decomposition of the salts. The solid product is fired to create a fired product containing a ceria-zirconia-based regular array phase precursor and an aluminate-based composite oxide precursor. A reducing heat treatment is performed on the fired product to obtain a first composite that has mutually dispersed therein a pyrochlore phase and an aluminate-based composite oxide. Finally, an oxidizing heat treatment is applied to the first composite to obtain a second composite in which at least part of the pyrochlore phase is transformed into a β phase, resulting in an oxygen storage material that has mutually dispersed therein the composite oxide and the regular array phase. Another notable patent is for a ceria-zirconia complex oxide material and method for producing the same, which provides a satisfactory oxygen storage material comprising zirconia particles with a ceria-zirconia complex oxide supported on them.
