Abstract

The present invention provides a method for producing metal-supported carbon, which includes supporting metal microparticles on the surface of carbon black, by a liquid-phase reduction method, in a thin film fluid formed between processing surfaces arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, as well as a method for producing crystals comprising fullerene molecules and fullerene nanowhisker/nanofiber nanotubes, which includes uniformly stirring and mixing a solution containing a first solvent having fullerene dissolved therein, and a second solvent in which fullerene is less soluble than in the first solvent, in a thin film fluid formed between processing surfaces arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other.

First claim

The invention claimed is:

1. A method for producing crystals comprising fullerene molecules and fullerene nanowhisker/nanofiber nanotubes, the method comprising uniformly stirring and mixing a solution containing a first solvent having fullerene dissolved therein, and a second solvent in which fullerene is less soluble than that in the first solvent, in a thin film fluid formed between processing surfaces arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other.

2. The method for producing crystals comprising fullerene molecules and fullerene nanowhisker/nanofiber nanotubes according to claim 1 , wherein a solution in which one or more precursors of a metal capable of serving as a catalyst are dissolved in said second solvent in which fullerene is less soluble is used, whereby a catalyst is supported by or included in the fullerene crystals.

3. The method for producing crystals comprising fullerene molecules and fullerene nanowhisker/nanofiber nanotubes according to claim 1 , wherein a solution obtained by adding a platinum derivative of fullerene to the solution containing a first solvent having fullerene dissolved therein is used, whereby a catalyst is supported by or included in the fullerene crystals.

4. The method for producing crystals comprising fullerene molecules and fullerene nanowhisker/nanofiber nanotubes according to claim 1 , wherein the fullerene molecules are metal-included fullerene or a fullerene derivative.

5. The method for producing crystals comprising fullerene molecules and fullerene nanowhisker/nanofiber nanotubes according to claim 1 , wherein the products have a closed shape or a shape with an open hole.

6. The method for producing crystals comprising fullerene molecules and fullerene nanowhisker/nanofiber nanotubes according to claim 1 , further comprising:
introducing the first solvent and the second solvent into a processing device, wherein the reaction comprises:
a fluid pressure imparting mechanism for imparting predetermined pressure to a fluid to be processed;
at least two processing members of a first processing member and a second processing member, the second processing member being capable of approaching to and separating from the first processing member, the at least two processing members providing said processing surfaces, said processing surfaces including a first processing surface and a second processing surface which are faced with each other;
a rotation drive mechanism for rotating the first processing member and the second processing member relative to each other;
a first flow path being a sealed flow path, wherein each of the processing surfaces constitutes part of the sealed flow path through which one of the first solvent and the second solvent under the predetermined pressure is passed into a space between the first and second processing surfaces; and
a second flow path independent of the first flow path through which the other of the first solvent and the second solvent is passed into the space between the first and second processing surfaces, wherein the second flow path forms at least one opening in at least either the first processing surface or the second processing surface,
wherein the first solvent and the second solvent, at least one of which contains a reactant, are uniformly mixed and positively reacted between the processing surfaces,
wherein, of the first and second processing members, at least the second processing member is provided with a pressure-receiving surface, and at least part of the pressure-receiving surface is comprised of the second processing surface, and
wherein the pressure-receiving surface receives pressure applied to the fluid by the fluid pressure imparting mechanism thereby generating a force to move in the direction of separating the second processing surface from the first processing surface;

mixing and positively reacting the first solvent and the second solvent in the space between the first and second processing surfaces to form the thin film fluid; and
introducing a third fluid other than the first solvent and the second solvent to enable a state of desired reaction by mixing under uniform stirring in the thin film fluid.
