摘要： An object of the present invention is to provide an exhaust gas purification catalyst which can exhibit sufficient purification performance even under a high Ga condition. The present invention relates to an exhaust gas purification catalyst comprising a substrate and a catalyst coating layer formed on the substrate, wherein the catalyst coating layer comprises catalyst particles, the catalyst coating layer having an upstream region extending by 40 to 60% of the entire length of the substrate from an upstream end of the catalyst in the direction of an exhaust gas flow and a downstream region corresponding to the remainder portion of the catalyst coating layer, the composition of the catalyst particle of the upstream region being different from that of the downstream region. The downstream region in the direction of an exhaust gas flow has a structure where a void is included in a large number, and furthermore high-aspect-ratio pores having an aspect ratio of 5 or more account for a certain percentage or more of the whole volume of voids. Thus, the exhaust gas purification catalyst exhibits enhanced purification performance.

摘要： There is provided a technique that suppresses a variation in particle diameter of a metal catalyst in the process of supporting the metal catalyst on a carrier. A CNT substrate having carbon nanotubes (CNTs) as the carrier arrayed thereon is placed in a processing chamber. Carbon dioxide is supplied to the processing chamber. After the carbon dioxide in the processing chamber is made supercritical, a complex solution in which a platinum complex is dissolved is supplied to the processing chamber. A sample temperature denoting temperature of the CNTs is controlled to be higher than an ambient temperature in the processing chamber. The CNT substrate is heated, such that a temperature difference between the ambient temperature and the sample temperature repeats increasing and decreasing. After the state of the supercritical fluid is changed to a non-supercritical state, the CNT substrate is heated, so as to cause the metal catalyst to deposit on the surface of the CNTs.

摘要： The invention provides a process for the production of titania particles with a desired morphology. The process comprises providing a titania sol and then drying the sol to provide dried titania particles. The process is characterised in that the morphology of the dried titania particles is controlled by applying one or more of the following criteria: (a) the titania sol is produced from a TiO2 containing slurry obtained using a precipitation step in a sulphate process, wherein the size of micelles formed during the precipitation is controlled; (b) the titania sol is produced from a TiO2 containing slurry and the pH of the slurry is controlled in order to affect the extent to which the titania sol is flocculated; (c) the titania sol is produced from a TiO2 containing slurry and the iso-electric point of the titania is adjusted in order to affect the extent to which the titania sol is flocculated; (d) the titania sol is dried by application of heat and the temperature used during the drying step is controlled.
