    摘要： A catalyst assembly comprising a substrate, nanofilaments which have a nanometer-size diameter and are formed on the substrate, and particles which have a nanometer-size diameter, at least one of the nanofilaments and the particles having a catalytic function, is provided to use a catalyst more efficiently and to provide a catalytic function more efficiently. Interstices between the nanofilaments serve as distribution channels of a reactive gas, and the reactive gas spreads sufficiently not only around the ends of nanofilaments but also inside a catalyst assembly. A combination of nanofilaments and particles enables dispersion of a catalyst at a distance of not more than about 100 nanometers.

    摘要： A process for production of a mesoporous structure wherein fine particles having a mean particle size smaller than the size of pores of a mesoporous body formed using a template are formed in the pores of the mesoporous body. The process comprises the steps of: preparing an aqueous solution comprising a mixture of the template and the fine particles, heating and pressurizing the aqueous solution to bring the water in the aqueous solution to a subcritical water state, returning the aqueous solution to a state at a room temperature and under atmospheric pressure, dissolving the starting material of the mesoporous body in the aqueous solution and heating it to form a precipitate comprising the template, fine particles and starting material of the mesoporous body, and separating, drying and firing the precipitate to burn off the template from the precipitate.
