The present invention relates to a method of methane steam reforming using a nickel/alumina nanocomposite catalyst. More specifically, the present invention relates to a method of carrying out methane steam reforming using a nickel/alumina nanocomposite catalyst wherein nickel metal nanoparticles are uniformly loaded in a high amount on a support via a melt infiltration method with an excellent methane conversion even under a relatively severe reaction condition of a high gas hourly space velocity or low steam supply, and to a catalyst for this method. In addition, the present invention prepares a nickel/silica-alumina hybrid nanocatalyst by mixing the catalyst prepared by the melt infiltration method as the first catalyst and the nickel silica yolk-shell catalyst as the second catalyst, and applies it to the steam reforming of methane to provide a still more excellent catalytic activity even under the higher temperature of 700&#xb0; C. or more with the excellent methane conversion.

Provided are particle size-controlled, chromium oxide particles or composite particles of iron oxide-chromium alloy and chromium oxide; a preparation method thereof; and use thereof, in which the chromium oxide particles or the composite particles of iron oxide-chromium alloy and chromium oxide having a desired particle size are prepared in a simpler and more efficient manner by using porous carbon material particles having a large pore volume as a sacrificial template. When the chromium oxide particles or the composite particles of iron oxide-chromium alloy and chromium oxide thus obtained are applied to gas-phase and liquid-phase catalytic reactions, they are advantageous in terms of diffusion of reactants due to particle uniformity, high-temperature stability may be obtained, and excellent reaction results may be obtained under severe reaction environment.
