Method for simultaneously preparing iron phosphate with micro-nano porous structure and 5-hydroxymethylfurfural, and obtained material and application thereof

Abstract

The invention discloses a method for simultaneously preparing iron phosphate (FePO4) with a micro-nano porous structure and 5-hydroxymethylfurfural (5-HMF), and an obtained material and application thereof. The method comprises the following steps: with deionized water and ethanol as solvents, a ferric iron salt and a phosphate radical-containing compound as raw materials and carbohydrate as a morphology guiding agent and a surfactant, conducting uniform mixing, performing one-step reduction by adopting a hydrothermal reaction method, filtering a product to obtain a liquid 5-HMF, and washing and drying a solid to obtain the iron phosphate with the micro-nano porous structure. Compared with a traditional preparation method, the method is simple, rapid and green to operate, the prepared ironphosphate with the micro-nano porous structure is uniform in morphology and has the micro-nano porous structure, and large-scale production can be achieved. The iron phosphate with the micro-nano porous structure prepared by the method has the advantages of porosity, large specific surface area and the like, has excellent electrochemical performance and can be applied to a positive electrode material of lithium ion battery. The liquid obtained by the reaction is 5-HMF with high purity, and can be used as a biological energy material.

Problems solved by technology

However, in the process of preparing 5-HMF, many studies use organic reagents such as DMSO, which not only increases the production cost, but also generates toxic reagents such as formaldehyde in an acidic and high-temperature environment, posing a threat to operators and the environment.
