Abstract

The invention relates to a preparation method of nitrogen doped and graphene loaded Cu-Cu2O nanocomposites. Copper phthalocyanine is used for providing a nitrogen source and a copper source, and the high-heat treatment is performed on mixed powder of the copper phthalocyanine and oxidized graphene in an argon atmosphere, so as to prepare the nitrogen doped and graphene loaded Cu-Cu2O nanocomposites. In the prepared nitrogen doped and graphene loaded Cu-Cu2O nanocomposites, Cu-Cu2O nanoparticles are loaded on nitrogen doped graphene sheets. The preparation method provided by the invention has the advantages of safety and simplicity, the yield is high and the recurrence and the industrial production are easy. The nitrogen doped and graphene loaded Cu-Cu2O nanocomposites which are produced by adopting the preparation method have good application prospects and economic values in aspects of photocatalysis, oxygen catalysis, supercapacitors and the like.

Description

Background technique [0002] Cu-Cu 2 O nanocomposites have special interface structures and electronic properties, low cost, and excellent performance, and have potential applications in the fields of information, catalysis, electronics, and energy storage. Therefore, Cu-Cu 2 O nanocomposites have received extensive attention and research. In 2011, Zhou Bo et al. (Bo Zhou, Hongxia Wang, Zhiguo Liu et al., Enhanced photocatalytic activity of flowerlike Cu 2 O / Cu prepared using solvent-thermal route[J],Materials Chemistry and Physics,126(2011)847-852.) Cu-Cu prepared by solvent thermal route 2 O nanocomposite material, and confirmed that the composite material has a good photocatalytic ability for the degradation of the dye Procean red. However, the solvothermal method it adopts...
