摘要： A fine spherical particle formed of diamond as a core and having carbon nano-materials radially grown therefrom is disclosed, which exhibits the appearance of a Marimo (Cladophora sauteri) particle. Fine diamond catalytic particles 2 whose surfaces are oxidized and treated to carry a transition metal catalyst are floated and stirred in a gas phase of hydrocarbon while being heated at a selected temperature to bring about a catalytic reaction which synthesizes carbon nano-materials and to grow them on the surface of said oxidized fine diamond particle. Nano fibers or filaments 32 of a nano size are grown from the fine diamond catalytic particle 31 as a core to form cladophora-form carbon. The carbon nano-materials if the supported transition metal is Ni or Co become carbon nano-tubes and if it is Pd become coin stacked carbon nano-graphite.

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： A method that allows producing hydrogen from methanol in a simple manner and an apparatus that is small in size and light in weight, which can produce hydrogen from methanol, are provided. The apparatus comprises a container (4) that retains liquid methanol (2) as a source material and gases (3) generated therein, a substrate (5) that is immersed in liquid methanol (2) in the container (4) loaded with a catalyst, and a power supply (6) for passing a direct or an alternating current through the substrate (5). The substrate may be made of an oxide or oxidized material, especially oxidized diamond, and loaded with a transition metal catalyst, especially Ni catalyst. With the substrate (5) heated, a novel catalytic methanol decomposition reaction occurs by a combination of abrupt temperature gradient directing towards methanol from the surface of the substrate, a catalysis of the oxide or oxidized material of the substrate and a catalysis of the catalyst loaded on the substrate, and a large amount of hydrogen gas is produced.
