Abstract

The invention discloses a method for preparing a compound material. The method comprises the following steps that 1, graphene oxide, soluble ferric iron salt and ferrous magnetic metal salt are used as raw materials, and a one-step in-situ method is used for preparing a ferromagnetic / graphene nanometer compound material, wherein the ferrous magnetic metal salt is Zn salt, Co salt, Ni salt, Mn saltor Cu salt; 2, fiber surface degreasing treatment is conducted, a fiber preform is woven, electrochemical immersion is conducted to prepare a metal-based compound material, and an organic solvent method or a heating method is adopted for treatment if a metal material is used; 3, the ferromagnetic / graphene nanometer compound material is loaded onto an electrode surface, by means of an electrochemical deposition method, precious metal is deposited on the surface of the compound material, and an electrochemical sensor based on a magnetic nanometer compound material base is obtained.

Description

technical field [0001] The invention relates to a method for preparing a material, in particular to a method for preparing a composite material. Background technique [0002] Hydrogen peroxide (H2O2) has strong oxidizing properties. As an efficient disinfectant and bleaching agent, it is widely used in food hygiene, environmental protection, textile, chemical and other fields. However, excessive residues of H2O2 will cause serious harm to human health and the ecological environment. , such as oxidizing human cells to accelerate aging, causing human genetic material to mutate or gene mutation; promoting the formation of acid rain, seriously destroying vegetation; causing the death of fish and shrimp and causing serious losses to the aquaculture industry. Therefore, it is particularly important to detect H2O2 accurately, quickly and sensitively. [0003] At present, methods for measuring H2O2 include spectrophotometry, chemiluminescence, fluorescence photometry, and chromatog...
