    摘要: A process for preparing a cobalt-containing hydrocarbon synthesis catalyst includes calcining an initial catalyst precursor comprising a catalyst support supporting a cobalt compound, by heat treating the initial catalyst precursor under non-reducing conditions in order to decompose the cobalt compound and/or to cause the cobalt compound to react with oxygen, thereby to obtain a calcined initial catalyst precursor. A cobalt compound is introduced onto and/or into the calcined initial catalyst precursor so that the calcined initial catalyst precursor supports this cobalt compound thereby obtaining a subsequent catalyst precursor. The subsequent catalyst precursor is directly subjected to reduction conditions to activate the subsequent catalyst precursor, thereby to obtain a cobalt-containing hydrocarbon synthesis catalyst.

    摘要: A novel carbon nanotube (64) is featured in that it has the highest Raman scattering intensity in the vicinity of 1580 cm−1 in its Raman spectrum. Carbon nanotubes can be grown on and from the catalytic fine particles (63) which consist of ultra-fine particles of cobalt oxide catalyst onto a substrate comprising a conductive substrate (62) and fine particles (63) of catalyst formed on a surface thereof. An electron emission device (60) so configured as to emit electrons by applying a voltage to apical ends (64a) of such carbon nanotubes (64) can be reduced in driving voltage and can achieve a current such as to emit a fluorescent material on the market for low-velocity electron beams. The electron emission device (60) needs no gate and can thus simplify the structure and reduce the cost of a surface light-emitting device for which the element is used. The carbon material remains unoxidized even in a low vacuum and thus allows realizing a light emitting device that can be paneled more easily, and is longer in operating life than those using a conventional electron emission device.

    摘要: It is intended to highly efficiently produce a high-density brush shaped carbon nanostructure useful in the production of CNT assembly, such as rope-shaped CNTs, and provide a catalyst body for production of brush-shaped carbon nanostructure that enables the production. The catalyst body for production of brush-shaped carbon nanostructure is one comprising a substrate (32), an aggregation suppressive layer (34) superimposed on a surface thereof and a catalyst layer superimposed on the aggregation suppressive layer (34). The catalyst layer is a catalyst particle layer (44) consisting of metallic catalyst particles (42) composed mainly of a catalytic metal. The metallic catalyst particles (42) have an average particle diameter, D, satisfying the relationship 0.5 nm≦D≦80 nm, and individual particles of the metallic catalyst particles (42) have a diameter, d, falling within the range of the above average particle diameter (D). Further, there are disclosed a process for producing the catalyst body, a brush-shaped carbon nanostructure and a process for producing the same.

    摘要: Methods and compositions relate to a Fischer-Tropsch catalyst utilized to convert syngas into paraffins. The catalyst includes a given amount of sulfur content from contact of a catalytic supported metal with sulfur. Subsequent activation of the catalyst prepares the catalyst to be used for conversion of the syngas. The sulfur content maintained in the catalyst after being activated influences selectivity to paraffins over olefins and oxygenates.

    摘要: Titania having high visible light photocatalytic activity is prepared by (a) mixing titania with carbon powder; (b) heating the titania/carbon powder mixture to at least about 1000° C. in an inert or weakly reactive atmosphere; and (c) thereafter heating the resultant powder mixture to a temperature in the range of about 350 to about 1000° C. in an oxidizing atmosphere. The resultant titania may be used for detoxifying or disinfecting liquids for gases, for generating hydrogen from aqueous media and in sunscreens and sunglasses.
