Problems solved by technology

However, the pre-treatment of graphene is more complicated. The synthesis process will use toxic and harmful oxidizing agents and reducing agents. At the same time, it needs to pass inert gas under high temperature environment, which increases the production cost and limits its application in actual production.

Embodiment 1

[0030] Peel the radish and cut it into a size of 2cm*3cm*4cm, put it into a reaction kettle and conduct a hydrothermal reaction at 180°C for 18h.

[0031] The material obtained by the reaction was first washed with distilled water, then soaked and washed twice with ethanol aqueous solution at 40°C to 45°C, then cooled to room temperature, and finally washed once with distilled water to obtain a biomass charcoal-based wet gel.

[0032] Weigh 0.02g of cetyltrimethylammonium chloride (CTAC) and dissolve it in 20mL of distilled water, ultrasonically shake it to dissolve completely, then add 12g of biochar-based wet gel and 0.025g of silver nitrate , reacted in a constant temperature water bath at 40°C to 45°C for 10 hours in the dark, and obtained a precipitate after the reaction—a carbon aerogel with silver chloride attached to the hole.

Abstract

The invention discloses a preparation method of a silver sulfide loaded radish derived carbon aerogel material, and belongs to the technical field of nanometer materials. The method comprises the steps that radish is used as a raw material to prepare biomass carbon aerogel; silver nitride precipitation is generated from chloride ions in cetyltrimethylammonium chloride and silver ions in silver nitrate and attached to holes in the carbon aerogel; silver chloride in the holes in the carbon aerogel reacts with sodium sulphide to generate silver sulfide more difficult to dissolve; washing and frozen drying are carried out, and the silver sulfide loaded radish derived carbon aerogel material with the strong loading fastness is obtained. The material is applied to processing dye wastewater, waste resource utilization is achieved, the dye wastewater can be effectively processed, and the purpose of changing waste into wealth is achieved.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a preparation method of carbon airgel materials. Background technique [0002] As a lightweight nanoporous material, carbon aerogel has broad application prospects in the fields of catalysis, adsorption, electrode materials, environmental protection, and energy storage because of its high porosity and large specific surface area. The traditional carbon aerogel preparation method is prepared by carbonizing phenolic organic aerogels, which requires a series of operations such as high-temperature carbonization and supercritical drying processes, and phenols and aldehydes are very toxic and have great harm to the body and the environment. of danger. [0003] At present, the new type of carbon aerogels prepared from biomass has become a new research hotspot. Due to the abundant apparent groups on its surface, such as C=C, C=O, -OH, C-O-C, etc. Modification, c...
