Problems solved by technology

At present, most of the design and preparation of porous carbon is based on the traditional hard template method and soft template method. These methods can effectively control the morphology and pore size of carbon materials, but the preparation process is cumbersome and costly, which is not conducive to large-scale Production scale

Abstract

The invention discloses a preparation method of a biomass carbon material doped with molybdenum phosphide nanoparticles with a pore network structure. The impregnated Enteromorpha is obtained by impregnating the decolorized Enteromorpha in an ammonium molybdate solution for a period of time, and the impregnated Enteromorpha Moss is heated to 350±10°C under the protection of inert gas for pre-carbonization for a period of time, and then heated to 700±10°C for carbonization to obtain oxide-doped porous carbon composite material MoO x / HPC, will MoO x / HPC and sodium hypophosphite are subjected to phosphating treatment for at least three times, wherein the phosphating treatment condition is to raise the temperature to 300±10° C. under an inert atmosphere. In the preparation method, enteromorpha is used as a carbon source, and the molybdenum phosphide-doped biomass porous carbon with a pore network structure is prepared by one-step in-situ conversion. Not only is the cost low, the reaction process is simple, green and the yield is high, it can achieve tonnage-level production, but it also helps to expand the application field and scope of natural biomass.

Description

technical field [0001] The invention belongs to the field of synthesis of inorganic nanometer materials, and in particular relates to a method for preparing a biomass carbon material doped with molybdenum phosphide nanoparticles with a pore network structure. Background technique [0002] In recent years, a variety of water pollutants caused by the rapid development of human society have received great attention, mainly including heavy metal ions, chemical toxins, petroleum derivatives, dyes and others. Among them, dye wastewater is mainly discharged by industries such as textiles, plastics, and papermaking, and the annual discharge accounts for about 20% of the total industrial wastewater. Dyes are mainly composed of complex aromatic compounds, which have potential carcinogenic and mutagenic effects, and high Chemical stability and strong resistance to biodegradation make it difficult to be degraded under natural conditions. Therefore, it is imminent to research and develo...
