Abstract

The invention discloses a method for using metallic copper to carry out in-situ modification on mesoporous organic polymer or carbon material. The method comprises the following steps of: fully stirring and mixing mesoporous organic polymer, mineralizer, copper source, acid and water according to mass ratio of 1.0 to 5.0 : 0.5 to 3.5 : 1.0 to 6.0 : 1.0 to 2.0 : 6, putting the mixture in a sealed container, heating at the temperature 80 to 120 DEG C for two days in water, washing the obtained precipitates with deionized water after filtering the precipitates, drying and then obtaining the mesoporous organic polymer material modified by copper oxalate; baking the material in nitrogen atmosphere at the temperature 400 DEG C to 500 DEG C or 500 DEG C to 900 DEG C; and obtaining the mesoporousorganic polymer or carbon material modified by metallic copper. The method has simple steps and easy operation and is beneficial to industrialized production; and the obtained organic polymer or carbon material has good hydrogen storage property in charging and discharging experiments and can be used as excellent electrode material.

Description

technical field [0001] The invention relates to the technical field of inorganic porous materials, in particular to a method for in-situ modification of mesoporous organic polymers or carbon materials by metal copper. Background technique [0002] Mesoporous materials have a large pore size, specific surface area, and regular pore structure, and are widely used in catalysis, adsorption, and other fields. Organic polymer mesoporous material is a new type of material whose skeleton is an organic polymer. It has great potential in many high-tech fields such as separation, catalysis, adsorption, sensing, microelectrophoresis, dielectric materials and bioreactors. application prospects. Ordered carbon mesoporous materials are a kind of non-silicon-based mesoporous materials with uniform pore size, highly ordered pore distribution, huge specific surface area and pore volume, and can be used as hydrogen storage materials, macromolecular catalytic reaction carriers, electrodes, etc...
