NANOPOROUS CATALYST PARTICLES, THE PRODUCTION THEREOF AND THEIR USE |
摘要 |
The invention relates to nanoporous catalyst particles having a spherical and/or spheroidal secondary structure, which contain, as catalytically active constituents, transition metals and/or oxides or precursors thereof. The invention also relates to a method for producing the nanoporous catalyst particles, during which, by means of a precipitation process, precursors with a spherical and/or spheroidal preliminary shape are produced from soluble compounds of the active constituents, and these morphologically pre-shaped precursors are, in a thermal activation step, transformed into nanoporous catalyst particles having a spherical and/or spheroidal secondary structure. The inventive catalyst particles can be used in the production of ceramic materials, as electrode materials in electrochemical cells or in fuel cells, as storage materials for chemical species and, in particular, in the production of carbon nanoparticles in the form of small tubes or fibers. |
