A method of production of core/shell type nanoparticles includes the following steps: a first step of applying a first power to cause the generation of the plasma so as to selectively cause the precipitation of a first metal so as to form nanoparticles as cores and a second step of applying a second power which is larger than the first power to cause the generation of the plasma so as to cause the precipitation of a second metal which has a smaller oxidation reduction potential than the first metal on the core surface so as to form shells which are comprised of the second metal which cover the cores which are comprised of the first metal.

A particulate inorganic oxide containing aluminum oxide, a metal oxide forming no composite oxide with aluminum oxide, and an additional element including at least one of a rare-earth element and an alkali earth element, the inorganic oxide containing a secondary particle formed by aggregating primary particles; wherein at least a part of the secondary particle includes a plurality of first primary particles, each having a particle size of 100 nm or less, containing aluminum oxide and the additional element, and a plurality of second primary particles, each having a particle size of 100 nm or less, containing the metal oxide and the additional element; wherein at least a part of the first and second primary particles has a surface concentrated region where the additional element has a locally increased content in a surface layer part thereof.

Inorganic oxide, exhaust gas purifying catalyst carrier, and exhaust gas purifying catalyst

The catalyst carrier in accordance with the present invention is a catalyst carrier comprising a support containing an oxide and an element in group 3A of the periodic table, and a coating part covering at least a part of a surface of the support; wherein the coating part contains an element in group 3A of the periodic table; and wherein the element in group 3A contained in the coating part has a concentration higher than that of the element in group 3A contained in the support. In this case, even when a catalyst in which rhodium is supported by the catalyst carrier is used for a long time in a high temperature environment, the grain growth of rhodium particles can be suppressed, and the catalyst can fully be prevented from lowering its activity.

Catalyst carrier and catalyst using the same

A catalyst for purifying exhaust gases includes a carrier substrate and a catalyst layer which is carried on the carrier substrate and contains a noble metal, a porous oxide and an additional oxide containing at least one selected from the group consisting of Ni, Bi, Sn, Fe, Co, Cu and Zn. Only a downstream section of the carrier substrate, which is located on a downstream side of an exhaust gas stream contains the additional oxide, whereas an upstream section of the carrier substrate does not contain the additional oxide. With this arrangement, in the upstream section of the carrier substrate, the noble metal and the additional oxide do not exist together so that the noble metal is not deteriorated with the additional oxide. As a result, in the upstream section, the purification performance as a three-way catalyst is favorably achieved, thereby restraining the emission of HS while maintaining the three-way performance.

According to the present invention, the state of a liquid fuel such as diesel fuel is made a supercritical state by raising the pressure and the temperature of the fuel above the critical pressure and temperature. Then, the fuel is injected from the fuel injection valve into the combustion chamber of the engine in the supercritical state. When the fuel in the supercritical state is injected into the combustion chamber of the engine, it forms an extremely fine uniform mist in the entire combustion chamber. Therefore, the combustion in the engine is largely improved.
