Description
Technical Field
The invention belongs to the technical field of preparation of nano composite materials, and particularly relates to a nano iron oxyhydroxide/metal/graphene ternary composite material and a preparation method thereof.
Background
The graphene material has the characteristics of large specific surface area, excellent physical properties, adjustable surface chemical properties and the like, and is concerned in recent years. Graphene oxide, which is an important member of a graphene family, shows good hydrophilicity due to the rich oxygen-containing functional groups, while the carbon of the main sheet layer makes the graphene oxide have certain hydrophobicity, and the performance of the graphene oxide is close to that of a two-dimensional surfactant, so that the graphene oxide already shows certain interfacial activity. However, the acid-base stability and the thermal stability of the graphene oxide are poor, so that the application of the graphene oxide in the aspect of interfacial catalysis organic chemical reaction is limited. The hydrophilic and hydrophobic solid particle hybridization synergistic effect can play a role in surface activity regulation, and the solid nanoparticles have more excellent thermal stability and acid and alkali stability compared with organic functional groups, so that a new idea is provided for graphene oxide interface regulation.
However, in the prior art, graphene is used as a carrier material of a catalyst, and the loading of metal nanoparticles is mainly achieved by an immersion reduction method, a precipitation method, a deposition-precipitation method, and the like. In the reduction process of these methods, a liquid phase chemical reduction method using highly toxic hydrazine, hydrazine hydrate or the like as a reducing agent or a high temperature reduction method using a gas such as hydrogen, carbon monoxide or the like is generally used. The methods can not effectively control the size, the dispersity and the loading capacity of the loaded metal nanoparticles, and the loaded metal nanoparticles have poor binding force with the matrix, so that the interfacial activity of the surface of the graphene is weakened, and the metal nanoparticles are easy to fall off from the matrix or agglomerate in the catalytic process, thereby reducing the catalytic activity. In fact, in these conventional methods, the biggest problem faced is that graphene is irreversibly agglomerated during the preparation process, and monodisperse graphene is not easily obtained; the interaction between the catalyst nanoparticles and the carrier is weak, graphene is difficult to be agglomerated together, and most of reported graphene sheets modified by the metal nanoparticles are in an aggregation state. Therefore, the huge specific surface area of the graphene cannot be fully utilized, and the synergistic catalytic action of the compound cannot be fully exerted.
