Problems solved by technology

However, due to the limitation of the volume of the polyhydroxymetal cation itself, it is used as a pillar propping agent to synthesize the zirconium phosphate layered column material. The obtained layered column material has a small pore size and has the disadvantages that the column structure is not easy to control and the regularity of the laminates is destroyed. , so that the materials obtained by this kind of synthetic method are limited in the application of shape-selective adsorption and selective catalysis

Abstract

The invention discloses a method for preparing a zirconium phosphate layer column material by a guide assembly technology, and belongs to the technical field of preparation of materials. The method comprises the following steps: organically modifying layered zirconium phosphate which is used as a raw material by long-chain organic amine such as cetylamine, intercalating long-chain quaternary ammonium salt such as dodecyl dimethyl benzyl ammonium chloride into the organized zirconium phosphate layer, synergetically introducing ethyl silicate and long-chain quaternary ammonium salt by a solvation method, forming a silica polymer cross-linked structure which is arranged in order in the zirconium phosphate layer by the guide assembly technology with the micelles formed by the long-chain quaternary ammonium salt such as dodecyl dimethyl benzyl ammonium chloride as a template, and removing the organic amine and quaternary ammonium salt by calcination to obtain the zirconium phosphate layer column material supported by a silicon dioxide column.

Description

technical field [0001] The invention relates to a method for preparing a zirconium phosphate layer column material by using a guided assembly technology, and belongs to the technical field of material preparation. Background technique [0002] In recent years, relying on layered compounds with a two-dimensional spatial structure as the main skeleton, using the principle of intercalation assembly chemistry to introduce functional guests, construct a supramolecular intercalated column structure, and synthesize layered columns with a highly ordered structure and multiple excellent functions. Materials have attracted extensive attention of many chemical and material scientists, and become one of the active topics in the field of chemistry and material science research. [0003] The use of large-volume inorganic cations to prepare layered column materials by ion exchange in layered compounds originated from natural clay materials such as clay, hydrotalcite, and montmorillonite. ...
