Abstract

The invention provides a method for preparing and synthesizing a ferroferric-oxide-supported cobalt selenide magnetic nano composite material by a hydrothermal process and application thereof, belonging to the technical field of preparation and application of nano materials. The invention does not need to previously prepare any template or use any surfactant, has the advantage of mild reaction process, and is easy to control; and the obtained ferroferric-oxide-supported cobalt selenide magnetic nano composite material has high activities in catalyzing reduction of nitrophenol and adsorbing methylene blue. The result indicates that 1mg of ferroferric-oxide-supported cobalt selenide magnetic nano composite material can completely catalyze the nitrophenol in 0.1ml of 5.0*10<-3>M nitrophenol solution by only 13 minutes; and 50mg of ferroferric-oxide-supported cobalt selenide magnetic nano composite material can completely adsorb the methylene blue in 50ml of 5mg / L methylene blue solution by only 25 minutes. Besides, the prepared sample has magnetic property, thus, can be conveniently separated and collected with a magnet, and is convenient for recycling.

Description

Technical field:

[0001] The invention belongs to the technical field of nanomaterial preparation and application, and specifically relates to the preparation of a cobalt selenide magnetic nanocomposite material loaded with ferric oxide by a hydrothermal method. The material has the functions of efficiently catalyzing the reduction of p-nitrophenol and rapidly adsorbing methylene blue dye nature. Background technique:

[0002] Nanocomposites have superior physical and chemical properties than single components. There have been related reports on ferroferric oxide composite materials, such as the compounding of ferric oxide and graphene, the compounding of ferric oxide and silicon dioxide, silver, the compounding of ferric oxide and titanium dioxide, etc., but the compounding of ferric oxide The compounding of triiron and cobalt selenide has not been reported so far.
