METHOD FOR PREPARING HOLLOW NANOFIBER, HOLLOW NANOFIBER AND CATALYST COMPOSITION FOR PREPARING HOLLOW NANOFIBER
Document Type and Number:
WIPO Patent Application WO2003045843
Kind Code:
A9
Abstract:
A method for preparing a hollow nanofiber having carbon as a primary component, which comprises contacting a carbon-containing compound with a catalyst at a temperature of 500 to 1200˚C, wherein as the catalyst use is made of a catalyst comprising a zeolite exhibiting the thermal resistance at 900˚C and, carried thereon, a metal; a catalyst comprising a metallosilicate zeolite containing a heteroatom except aluminum and silicon in the structural skeleton thereof and, carried thereon, a metal; a catalyst comprising a carrier and, carried thereon, fine cobalt particles exhibiting a binding energy of a cobalt 2P3/2 electron of 779.3 to 781.0 eV, as measured by the X-ray photoelectron spectroscopy; a catalyst comprising a carrier and, carried thereon, fine cobalt particles exhibiting a cobalt atom ratio in the surface of the carrier of 0.1 to 1.5 %, as measured by the X-ray photoelectron spectroscopy under a condition of 10 kV and 18 mA; a catalyst comprising a carrier and, carried thereon, fine cobalt particles exhibiting a weight ratio of cobalt to a second metal component (weight of cobalt/weight of the second metal component) of 2.5 or more; or a catalyst comprising a zeolite having a film form and, carried on the surface thereof, a metal.
