Problems solved by technology

This method has inherent disadvantages that are difficult to overcome
First of all, a high-pressure hydrogen source is needed to "charge hydrogen"; secondly, from the point of view of the release of gas, the generation, maintenance, measurement and control of hundreds of degrees of high temperature, etc., require special working modules to solve, which not only increases It increases the complexity of technology and application cost, and it is very uneconomical from an energy point of view

Embodiment 1

[0057] The following examples illustrate the preparation process of the light-controlled gas source in detail.

[0058] (1) preparation conditions preparation:

[0059] 1) Preparation and selection of carbon nanotubes: carbon nanotubes were prepared by an arc discharge method. Ni and Yi particles are used as catalysts, graphite powder and graphite rods are used as carbon sources, helium is used as working gas, and arc discharge is performed at a pressure of 500 Pa, with a discharge current of 50-100 amperes. Carbon nanotubes grown in this way can be used with or without purification. Using concentrated nitric acid oxidation cutting technology to make the carbon nanotubes with closed ends into open tubes to facilitate water absorption. The basic requirement for carbon nanotubes is that the diameter of a single carbon nanotube is from 0.6nm to 10nm, and the length is greater than 100nm. The content of open carbon nanotubes (at least one end not covered by a fullerene cap) is ...

Abstract

The present invention is method of applying carbon nanotube in the field of energy source. By means of the 'super light absorbing effect' of nanometer material and the special existence state of water in carbon nanotube, water-containing carbon nanotube system is applied with light irradiation to generate H2, CO, CH4, C2H6 and other fuel gas. The present invention also proposes one kind of light controlled fuel gas preparing apparatus and its typical structures. The light controlled fuel gas preparing apparatus includes one vacuum container, carbon nanotube, electric light source and its control circuit, and valves for vacuumizing, feeding water vapor and taking fuel gas.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and relates to a new method for generating fuel gas by decomposing water through carbon nanotubes, in particular to a technology for manufacturing a new type of light-controlled gas source, as well as a light-controlled hydrogen source and a miniature hydrogen gas source for space designed based on the technology. The structure of thrusters, solar fuel cells and other devices. Background technique [0002] The development of all aspects of human society is inseparable from the support of energy technology. Currently the most used fossil energy is non-renewable. Therefore, for a long time, people have been carrying out unremitting scientific explorations, hoping to make full use of the inexhaustible solar energy and the ubiquitous water in nature to provide new energy sources. One of the ideas is to use the photovoltaic properties of semiconductor materials to convert sunlight energy int...
