Abstract

The invention relates to the technical field of compounds, in particular to a modified nano particle as well as a preparation method and application thereof. The modified nano particle comprise an inorganic nano particle, and a poly-o-phenylenediamine layer coating the surface of the inorganic nano particle. The applicant creatively discovers that the modified nano particle can catalyze the reaction of oxygen and water under a neutral condition (pH value is 7.0) to generate hydrogen peroxide; and a substrate TMB (3, 3 ', 5, 5'-tetramethyl benzidine) can be oxidized, so that an obvious absorption peak is generated at the 658 nm position of the ultraviolet-visible spectrum, and the unique oxidation-reduction type nano-enzyme catalytic activity is provided;.

Description

technical field

[0001] The invention relates to the technical field of compounds, in particular to a modified nanoparticle, its preparation method and application. Background technique

[0002] Aromatic polymers are the most commonly used semiconducting polymers. Their conjugated structures provide excellent electrical conductivity and electrochemical activity, and their electrical conductivity and dielectric properties can be tuned by controlling the proton doping state. Coupling plasmonics with active dielectrics holds promise for the development and design of multifunctional responsive smart materials, such as terahertz phase-modulated metamaterials. The surface of aromatic polymers (such as poly-o-phenylenediamine) is rich in amino and imine groups, making it easy to functionalize and modify, expanding its application range, such as in biosensing, metal ion adsorption, supercapacitors , Catalysis, sensing, electrochromic devices and many other fields.
