Embodiment 1

[0028] A preparation method of graphene modified carbon felt, comprising the following steps:

[0029] S1: Prepare a rack, install 10 grid plates on the rack, and the distance between the upper and lower grid plates is 2mm, then place the carbon felt on the grid plate, put the rack into the acid solution to soak, The grid plate is connected with the rack by clamping. The position of the grid plate can be adjusted. The rack is lifted up and down through the winding wheel and the traction rope. When the rack is pulled up, the rack is sprayed by the spray mechanism. When cleaning the carbon felt, the shelf can be cleaned at the same time. The soaking time is 5 hours. The acid solution is stored in a soaking box with an opening at the top. A filter screen is fixedly installed in the soaking box. The liquid pipe and the liquid discharge pipe are equipped with a liquid discharge valve, open the liquid discharge valve, and filter the acid solution through the filter screen, the filte...

Abstract

The invention belongs to the field of modified carbon felt production, and especially relates to a preparation method of a graphene modified carbon felt. For the problems of long preparation time andlow efficiency of the existing graphene-modified carbon felt, the following scheme is proposed, and the preparation method comprises the following steps of step S1, preparing a placing rack, mounting10 to 20 grating plates on the placing rack, wherein the distance between the upper and lower grating plates is 2 to 16 mm, placing the carbon felt on the grating plates, and putting a shelf into an acid solution for soaking; step S2, stirring the acid solution while soaking, enabling the acid solution to impact the carbon felt, accelerating the soaking speed, and cleaning sundries floating on thesurface of the acid solution while stirring; step S3, cleaning and drying the carbon felt after soaking, and then heating; and step S4, after heating, taking out the carbon felt, and cooling to roomtemperature to obtain the grapheme-modified carbon felt. The preparation method of the graphene-modified carbon felt provided by the invention can effectively shorten the preparation time of the graphene-modified carbon felt, and improve the preparation efficiency.

Description

technical field [0001] The invention relates to the technical field of modified carbon felt production, in particular to a preparation method of graphene modified carbon felt. Background technique [0002] Carbon fiber felt is a felt made of carbon fibers. It has a broad spectrum of adsorption and a large capacity. The adsorption capacity of organic vapors such as gasoline, aldehydes, phenols, alcohols, and olefins is several to dozens of times larger than that of activated carbon (GAC), and it has good adsorption for inorganic gases. (such as No, N, HF, HCl, etc.). [0003] After retrieval, the patent document with the application number 201710690586.2 discloses a preparation method of graphene-modified carbon felt, which solves the problem of poor conductivity, low specific surface area, low electrochemical activity, and vanadium ions in commercial carbon felt electrodes for vanadium batteries at the present stage. To solve the problems of poor catalytic performance, low...
