Embodiment 1

[0024] The preparation of embodiment 1 carbon nitride / copper oxide composite material:

[0025] Put 2.5g of melamine and 4g of copper acetate powder into a round bottom flask with 200ml of methanol as the solvent. Put the round-bottomed flask in a constant temperature magnetic stirrer, react for 3 hours, filter to obtain the precursor, put the prepared material into a porcelain boat, put it into a tube furnace, and heat up at a rate of 1 °C / min in an argon atmosphere. The room temperature was raised to 500° C. and kept at a constant temperature for 2 hours, and the argon flow rate was 60 cc / min. After cooling to room temperature, a nanoporous carbon nitride / copper oxide composite material is obtained.

Abstract

The invention discloses a synthesis method and an application of a porous carbonitride/copper oxide nanorod composite material with visible light response, and belongs to the fields of composite material preparation technologies and photocatalysis. The problems of small specific surface area, high photo-generated electron-hole recombination rate and low quantum yield of present carbonitride materials are solved in the invention. The composite material is prepared from melamine and copper acetate through a chemical reaction process and a heat treatment process with methanol as a solvent. Compared with carbonitride, the porous carbonitride/copper oxide nanorod composite material prepared in the invention has the advantages of high specific surface area, good photocatalysis performance, and effective degradation of rhodamine B under visible light. The preparation method has the advantages of simple process, cheap raw materials and large scale production; and the obtained composite material has large specific surface area, low photo-generated electron-hole pair recombination and good application prospect.

Description

technical field [0001] The invention relates to a composite material preparation method and photocatalytic application, in particular to a carbon nitride / copper oxide composite material preparation method and application, and belongs to the field of composite material preparation technology and photocatalysis. Background technique [0002] With the rapid development of industry, the discharge of waste water has brought an unprecedented crisis to people's living environment. In particular, a large amount of organic dye pollutants discharged in the printing and dyeing industry pose a great threat to the survival of people themselves and various organisms in the environment. Therefore, research on efficient, cheap, and repeatable photocatalysts to degrade organic dyes in water can reduce the discharge of environmentally harmful waste from industrial production, and then achieve sustainable social and economic development. [0003] Dyestuffs are widely used in many industries s...
