COMPOSITE BODY IN WHICH FIRST METAL-CONTAINING PARTICLES AND SECOND METAL-CONTAINING PARTICLES ARE SUPPORTED ON CARBON MATERIAL OR CONNECTED BY CARBON MATERIAL, AND METHOD FOR PRODUCING SAME

摘要

The present invention relates to a composite body in which first metal-containing particles and second metal-containing particles are supported on a carbon material or connected by a carbon material, and a method for producing the same. The above composite body can, if the first metal-containing particles exhibit a catalytic activity, be applied as a reaction catalyst and can also be used in various fields such as the manufacture of the adsorbent or the separation membrane.

1. A method for preparing a composite body in which first Size—controlled metal-containing particles and second size—controlled metal-containing particles are supported on a carbon material or connected by a carbon material, the method comprising the following steps:
a first step of mixing a first metal hydrate salt forming a first metal oxide, a second metal hydrate salt forming a second metal oxide, and a porous carbon material particle; a second step of melt-infiltrating the first metal hydrate salt and the second metal hydrate salt in the pores of the porous carbon material particle at a temperature that can melt the first metal hydrate salt and the second metal hydrate salt; optionally, a third step of drying the porous carbon material particles in which the first metal hydrate salt and the second metal hydrate salt are melt-infiltrated; a fourth step of of subjecting the resultant carbon material particles to high temperature calcination at a temperature and condition that thermally decompose the first metal hydrate salt, the second metal hydrate salt and the porous carbon material, thereby forming the first metal oxide particles and the second metal oxide particles in which the particle sizes are controlled by the pores of the porous carbon material, while forming a composite body in which the first metal oxide particles and the second metal oxide particles are supported or connected by the carbon material remaining after the thermal decomposition of the porous carbon material; and optionally, a fifth step of chemically changing the first metal oxide particles, the second metal oxide particles or both of them to the first metal-containing particles or the second metal-containing particles.
