A preparation method of a novel boron-doped graphene electrode for sewage treatment

Abstract

The invention discloses a method for preparing a novel boron graphene electrode for sewage treatment, comprising the following steps: A. using iron, platinum, cobalt or conductive glass as a substrate, and preparing a substrate sheet by chemical vapor deposition; B. Put the base sheet into a heating furnace under argon gas and preheat it for 4-6 hours; C. Add graphene and borobenzene to water, methanol, ethanol, and isopropanol solvents to form a mixture of graphene and borobenzene Solution; D. Under the control of the precision flow pump, inject the mixed solution of graphene and borobenzene into the closed reaction chamber through the capillary, slowly add the reaction chamber under the protection of argon, and react for 4-6 hours; E. After the reaction, stop Add the mixed solution of graphene and borobenzene, turn off the electric furnace and keep the flow rate of argon constant. The beneficial effects of the invention are: 1) the electrode greatly reduces the COD value of sewage; 2) the reaction speed is fast, and no toxic and harmful gas is generated during the process; 3) the reaction is efficient, non-toxic, and has no pollution to equipment.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a method for preparing a novel boron graphene electrode for sewage treatment. Background technique [0002] In recent years, with the development of the economy and the advancement of science and technology, the call for environmental protection has been increasing, and the standards for environmental protection have also been continuously improved. Higher standards have also been proposed for the treatment of a large amount of industrial wastewater and domestic sewage. Therefore, there are new problems to be solved urgently in sewage treatment, and new technologies for sewage treatment have emerged as the times require. Not only to greatly reduce the discharge of sewage, to protect the water environment, but also to save water. As a physical and chemical method, adsorption is an important treatment method in sewage treatment, which has the advantages of low cost, good selectivit...

Problems solved by technology

Since graphene sheets are prone to aggregation and are difficult to control in practical applications, it is difficult to obtain a large specific surface area for graphene-based assemblies, and it is even more difficult to achieve the theoretical specific surface area value of graphene of 2630m 2 / g, which greatly hinders the large-scale application of graphene as an adsorption material in industrialization
