Abstract

The invention relates to a method for preparing a CNT / Fe3O4@ZnO one-dimensional nanocomposite by a polyol one-pot method. The method comprises the following steps: 1, weighing and then mixing a multiwall nanotube, ferric acetylacetonate and triethylene glycol, then carrying out ultrasonic dispersion on the mixture until the mixture is uniform, then introducing argon, then heating the mixture to the boiling point of triethylene glycol and then carrying out reflux; and 2, then cooling the product to the room temperature, then throwing zinc acetate, then slowing heating the mixture to the boiling point of triethylene glycol, then carrying out reflux, carrying out magnetic separation after cooling, washing the product with ethanol and drying the product to obtain the CNT / Fe3O4@ZnO composite. The composite is applied in the fields of photoelectric device assembly and photocatalysis.

Description

technical field [0001] The present invention relates to a kind of CNT / Fe 3 o 4 Preparation methods of @ZnO one-dimensional nanocomposites. Background technique [0002] Carbon nanotubes (CNTs) have excellent mechanical, thermal, electrical properties and one-dimensional nanostructures, and have broad application prospects in nanoelectronic devices, reinforced composite materials, hydrogen storage materials, biomedicine, and catalysis. Ferroferric oxide nanoparticles have excellent magnetic properties and good biocompatibility, and can be used in fields such as magnetic fluids, targeted drug delivery, cancer hyperthermia, magnetic resonance imaging, and magnetic recovery carriers. At present, some researchers have assembled Fe on CNT 3 o 4 Nanoparticles endow CNTs with good magnetic responsiveness, and prepare them into magnetorheological fluids, electrode materials, targeted drug carriers, etc. [0003] Existing CNT / Fe 3 o 4 There are only magnetic properties and no o...
