Abstract

The invention belongs to the technical field of material preparation, and in particular relates to a method for preparing a sulfonic acid functionalized zirconium phosphate pillared layered material by using a hydrothermal fumigation technology. The method comprises the following steps: by using cetylamine-supported layered zirconium phosphate as a starting material, synergistically introducing a silicon source and a template agent between zirconium phosphate laminates through a solvent method; adjusting the pH to initiate rapid hydrolytic polycondensation of the interlayered silicon source; improving the firmness and stability of a zirconium phosphate interlayered silicon pillared structure through a hydrothermal method; filtering, drying and removing organic amine and the template agent; finally oxidizing a sulfhydryl group in a reactant by taking hydrogen peroxide as an oxidizing agent through a fumigation-oxidization technology to obtain the sulfonic acid functionalized silicon oxide pillared zirconium phosphate pillared layered material. A P-OH acid site on the surface of each zirconium phosphate laminate is well preserved, the Bronsted acid site is increased after sulfonic acid functionalization, and the ordered regularity of the laminate structure of the zirconium phosphate is well kept.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and in particular relates to a method for preparing a sulfonic acid functionalized zirconium phosphate layer column material by using hydrothermal and fumigation techniques. Background technique [0002] In recent years, the intercalation research of layered compounds has become more and more mature. On this basis, the concept of "pillared" was proposed. As a special method for activating layered compounds, it can effectively improve the structural properties of layered compounds such as interlayer spacing and specific surface area, thereby improving the catalytic effect of the material. [0003] Patent CN101475192A discloses a method for synthesizing layered columnar mesoporous titanium-silicon molecular sieves. This method first synthesizes the JDF-L1 microporous molecular sieve precursor, and then uses organic amines to increase the interlayer distance. Introduce organic silicon ...
