Problems solved by technology

Among the above methods, the preparation of metal-organic framework precursors mainly adopts hydrothermal or solvothermal methods, which are not conducive to large-scale industrial production.
Moreover, the magnetic nickel / carbon material prepared with a single nickel-based metal-organic framework material as a precursor has the disadvantage that the loading amount of metallic nickel is difficult to adjust

Abstract

The invention provides a preparation method of a magnetic nickel / carbon nanometer composite material and application thereof. The preparation method comprises the following steps of (1) preparation of a metal organic framework precursor: dissolving 1,3,5-benzene tricarboxylic acid into an alkaline water solution, adding an alcohol and water mixed solution of soluble metal salt, mixing and stirring at normal temperature, centrifuging, washing and drying, so as to obtain the metal organic framework precursor; (2) preparation of a magnetic carbon composite material: calcining the precursor obtained in step (1) under the inertia gas atmosphere, and cooling, so as to obtain the magnetic carbon nanometer composite material. The preparation method of the magnetic nickel / carbon nanometer composite material has the advantages that the method is simple, and the cost is low; the solvent heat synthesizing in the reaction kettle in the preparation process of the precursor of the magnetic nickel / carbon nanometer composite material is not needed, and the potential of batch production is realized.

Description

technical field [0001] The invention relates to a preparation method and application of a magnetic nickel / carbon nanocomposite material, in particular to a method for preparing a magnetic nickel / carbon nanocomposite material with a metal organic framework material as a precursor. Background technique [0002] Magnetic nickel / carbon nanocomposites are magnetic, and can be easily separated from other substances with a magnetic field, and are easy to recycle. At present, magnetic nickel / carbon nanocomposites have been widely studied as catalysts or adsorbents for the removal of organic matter and heavy metal ions from polluted water. [0003] Metal-organic frameworks generally refer to inorganic-organic hybrid porous materials with periodic network structures formed by the self-assembly of metal ions and organic ligands through coordination bonds. The magnetic nickel / carbon nanocomposite material can be obtained by calcining in an inert gas with the nickel-based metal organic ...
