PURPOSE: Metal nanoparticles dispersed in various porous supports, a method for preparing thereof, and a catalyst using thereof are provided to realize a metal nano catalyst of a high efficiency and a low price by reducing an amount of a reactive metal with maximizing a metal catalyst activation of a metal nanoparticle and simultaneously maintaining an activation for a long-term. CONSTITUTION: A method for preparing metal nanoparticles dispersed in various porous supports comprises the following steps: a metal precursor and a glyme are provided to a porous support; and the porous support is treated by heating. The porous support is a mesoporous silica. A heat treatment temperature is 110-220°C. A metal of a metal precursor is selected from a group consisting of palladium(Pd), nickel(Ni), iron(Fe), gold(Au), silver(Ag), and cobalt(Co). |
