Abstract

The invention discloses a method for preparing graphene carbon particles and preparing hydrogen by using an electrolyte in the technical field of hydrogen preparation by electrolyzing water. The method is characterized by comprising the following steps: preparing graphene-grade carbon particles by using a graphene-grade carbon particle preparation process method, mixing the graphene-grade carbon particles into composite conductive water to prepare graphene-based composite conductive water to prepare a hydrogen electrolyte, adding the electrolyte into an electrolytic cell to prepare hydrogen, and electrolyzing bubbles generated in the electrolysis process to obtain the graphene-based composite conductive water. According to the method for preparing the graphene carbon particles and the method for preparing the hydrogen from the electrolyte, a bubble blocking filter screen arranged below a water spray nozzle in an electrolytic cell is used for blocking rising of bubbles, water sprayed bythe water spray nozzle is used for cleaning filter paper at any time, and it is guaranteed that the filter paper smoothly discharges hydrogen or mixed oxyhydrogen gas, thus to provide a method for preparing graphene carbon particles and preparing hydrogen by using an electrolyte. The innovativeness of the invention is as follows: the process method for preparing the graphene-grade carbon particles can conveniently prepare the graphene-grade carbon particles, and when the graphene-grade carbon particles are used for preparing the hydrogen electrolyte, the electric quantity density can be increased, the resistance can be reduced, and the hydrogen preparation efficiency can be greatly improved.

Description

technical field [0001] The invention discloses a method for preparing graphene carbon particles and using the electrolytic solution to prepare hydrogen in the technical field of electrolyzing water to prepare hydrogen. Background technique [0002] In the prior art, it is difficult to achieve high-precision mass production of graphene-grade carbon particles by grinding or gas milling methods, and graphene-grade carbon particles have not yet been used in the production of hydrogen by electrolysis of water. And the present inventor has tested, when adding the granular carbon of micron order in alkaline aqueous solution, can make its electric resistance (R) reduce more than 3 times, and, the particle size g of carbon particle is little more and the amount m of blending reduces more The higher the multiple I (I=R / C.gm), and through further experiments, we have explored the process and method of washing graphite glaze balls to prepare graphene grade carbon particles. With the gra...
