Abstract

The invention relates to a preparation method of nitrogen and sulfur co-doping ordered mesoporous carbon materials. According to the method, pyrrole is used as carbon sources and nitrogen sources, sulfuric acid is used as acid catalysts and sulfur sources, pyrrole oligomers are used as precursors, mesoporous silica molecular sieves SBA-15 (space group P6mm) and KIT-6 (space group Ia3d) are used as templates, a primary wet impregnation method is combined with the high-temperature themolysis technology for preparing the nitrogen and sulfur co-doping ordered mesoporous carbon materials in two-dimensional orthohexagonal and three-dimensional cubic ordered mesostructures.

Description

technical field [0001] The invention relates to a preparation method of nitrogen and sulfur co-doped ordered mesoporous carbon material. Background technique Ordered mesoporous carbon (OMC) is a new type of carbon material that emerged in the 1990s, and there are mesoporous channels with uniform pore size in its structure. Compared with traditional porous carbon materials, ordered mesoporous carbon has the advantages of narrow pore size distribution, high porosity, and controllable pore size, and has broad application prospects in catalyst supports, hydrogen storage materials, adsorption separation, and electrode materials. . Its highly ordered structure can also be used to synthesize mesoporous zeolite molecular sieves and mesoporous transition metal oxides. Therefore, the preparation and application research of ordered mesoporous carbon materials has become the frontier and hotspot of current research on porous carbon materials. Recent studies have shown that heteroa...
