Method for producing metal-supported carbon, method for producing crystals consisting of fullerene molecules and fullerene nanowhisker/nanofiber nanotubes, and apparatus for producing the same

摘要

A method for producing metal-supported carbon 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.

1. A method for producing metal-supported carbon, comprising the steps of:
providing a first processing surface and a second processing surface 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; introducing a fluid to be processed, as a first fluid, between the first processing surface and the second processing surface; generating a force to move the first processing surface and the second processing surface in the direction of separating by pressure of the fluid to be processed; maintaining a minute space between the first processing surface and the second processing surface by the force; forming a thin film fluid out of the fluid to be processed passing through the first processing surface and the second processing surface, the minute space between the first processing surface and the second processing surface being maintained; supporting metal microparticles on a surface of carbon black in the thin film fluid, by a liquid-phase reduction method; providing a second fluid to be processed, wherein at least one of the first fluid and the second fluid contains a reactant, and the first and second fluids are uniformly mixed and positively reacted between the processing surfaces; providing a second flow path, for the second fluid, independent of a first flow path through which the first fluid is passed; and providing at least one opening leading to the second flow path, the at least one opening being arranged in at least either the first processing surface or the second processing surface, wherein the first fluid processing surface and the second processing surface are circular, one side of an outside and a center of the first processing surface and the second processing surface is an upstream side, and the other side is a downstream side, and at least one of the first processing surface and the second processing surface is formed with a groove-shaped depression extending from the upstream side to the downstream side, wherein the first fluid is introduced into the minute space between the first processing surface and the second processing surface by a micro-pump effect by rotation of the at least one of the processing surfaces provided with the groove-shaped depression, wherein the second flow path is configured such that an introduction of the second fluid through the at least one opening into the minute space between the first and second processing surfaces is toward a direction that is angularly offset with a first angle greater than 0° and less than 90°, in a rotation direction of either the first processing surface or the second processing surface, from a line which passes through a center rotation axis of either the first processing surface or the second processing surface and the at least one opening, and wherein the second flow path is inclined with respect to the first processing surface or the second processing surface, at a second angle more than 0° and less than 90°, and the at least one opening is positioned downstream at a point where a direction of flow of the first fluid is changed to a direction of flow of a spiral laminar flow formed between the both of processing surfaces.
