Abstract

The invention discloses a method for preparing a copper oxide nanocomposite material functionalized with perylene diimide. The steps are as follows: first dissolve water-soluble copper salt and sodium dodecylbenzenesulfonate into deionized water, stir and drop Add sodium hydroxide solution and continue stirring for 0.5 h; then aging at room temperature for 4 h to obtain a suspension. After drying for 6 h, centrifugation, washing, drying and calcination, copper oxide nanobelts were obtained. Then add the above-mentioned synthesized material into the N,N-dimethylformamide solution in which the perylene diimide is dissolved, and after ultrasonication, centrifuge, wash and dry to obtain the copper oxide-perylene diimide nanocomposite material. The present invention synthesizes perylene diimide functionalized copper oxide nanocomposites for the first time, and the method has the advantages of simple preparation process, low cost and mild reaction conditions; the nanocomposites prepared by the method have high purity and small size , good catalytic activity and so on.

Description

technical field [0001] The invention relates to a method for preparing a perylene diimide functionalized copper oxide (PDI-CuO) nanocomposite material, belonging to the technical field of nanocomposite material preparation. Background technique [0002] Transition metals have multiple valence states due to their special valence structure. Transition metal oxides corresponding to transition metals are also important functional materials and have a wide range of applications. Among them, copper oxide (CuO) has a narrow band gap of about 1.2 eV and is a typical p-type semiconductor. When the size of copper oxide particles reaches the nanoscale, there will be the unique quantum size effect, surface effect and macroscopic quantum tunneling effect of nanomaterials. For example, it shows extremely high catalytic activity as a photocatalytic material and is used as a photosensitive material in sensors. , and it can also be applied to thermally conductive materials and superconduct...
