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...
