Construction And Application Of Aminophenol Resin-based Composite Hollow Materials

Compared with solid materials,nano-hollow materials have the characteristics of large surface area,low density and high bearing capacity.Therefore,nano-hollow materials have special properties and wide applications in catalysis,drug transport,contrast agent,lithium-ion battery cathode and anode.Compounding hollow materials with other functional materials to construct micro-nano reactor with special structure is a novel research direction in the research of nano-hollow materials.In the micro-nano reactor,different components are organically combined,while maintaining their respective properties,they also have mutual assistance,thus showing the excellent performance of"one plus one is greater than two".However,the traditional method of constructing micro-nano reactor is more complex,which usually requires a number of cumbersome steps to synthesize.In this paper,aminophenol resin as a template,through the synergistic action with a variety of surfactants,can construct a variety of complex structures in one step.The main research contents are as follows:First,the core-shell nanorods,core-shell nanospheres,hollow nanospheres,yolk-shell nanospheres and multi-shell nanospheres were synthesized by hydrothermal method using 3-aminophenol as template and synergistic effect with F127 and CTAB surfactants.Using these five structures as anodes for lithium ion batteries,it is found that the hollow materials exhibit the best performance(capacity mAh·g^-1),and can still maintain capacity 851 mAh·g^-1 after 40 cycles,and the Coulomb efficiency can be more than 98.13%.Second,the bowl-shaped 3-aminophenol nanomaterials can be obtained by adding acetone to the synthesis process of 3-aminophenol.The surface of this material contains abundant amino groups,so it can stabilize metal nanoparticles with high loading and gold nanoparticles with more than 30 wt%stability.After loading gold nanoparticles,this material has excellent performance in macromolecular protein detection,and can effectively separate arginine,valine,lysine and glucose.When the concentration is 1mg/ml,the response of sodium ions to the four standard substances are all greater than 10000.
