Mesoporous alumina has broad application prospects and the industrial scale will continue to expand

Mesoporous alumina is a porous material with particle sizes in the nanometer range. Mesoporous alumina is a defective spinel structure. Due to the presence of defective sites and irregular pore structure, mesoporous alumina has high specific surface area, high porosity, high catalytic activity, strong adsorption performance, and good thermal stability. Features.

According to the “2023-2028 China Mesoporous Alumina Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , based on its advantages, mesoporous alumina has shown broad application prospects in catalyst carriers, ceramics, electronics, exhaust gas treatment, sewage treatment, sensor manufacturing, biomedicine, optics, catalysts, etc. However, the preparation conditions of mesoporous alumina are harsh and the process is complex, which limits its application expansion under certain circumstances.

Mesoporous alumina modified by functionalization has significant advantages in catalytic activity, stability, and selectivity. In recent years, with the improvement of industrial production requirements and the expansion of application fields, the application of traditional mesoporous alumina has been restricted, and functionalized Mesoporous alumina application needs released. In terms of classification, functionalized mesoporous alumina is mainly divided into metal oxide functionalization, bimetallic element functionalization, metal heteroatom functionalization, heteropolyacid functionalization, and organic metal complex functionalization.

In recent years, domestic and foreign researchers have conducted in-depth research on functionalized mesoporous alumina and have made great progress. In terms of preparation technology, the current main preparation methods for functionalized mesoporous alumina include in-situ synthesis, precipitation, impregnation, ion exchange, mechanical mixing, melting, etc. Among them, in-situ synthesis and impregnation are the most widely used. . In terms of application research, current application research on functionalized mesoporous alumina mainly focuses on catalyst carriers, biomedicine, etc.

With the acceleration of energy conversion, the development of the hydrogen energy industry has accelerated. However, hydrogen production by electrolysis of water, hydrogen production by natural gas, and biological hydrogen production all have difficult transportation and storage problems. As a new material, mesoporous alumina is expected to solve the problem of hydrogen energy storage and transportation. China Hydrogen Energy Technology Development (Inner Mongolia) Co., Ltd.’s “domestic first 1,000 tons/year mesoporous alumina production project” uses electrolytic aluminum as raw material and uses “active solid hydrogen storage material” technology to produce hydrogen and mesoporous dioxide. Aluminum, the successful commissioning of this project makes China Hydrogen Energy one of the few companies in the world that can mass-produce high specific surface area mesoporous nano-alumina.

Industry analysts said that mesoporous alumina is a new type of material. Based on its unique structure, mesoporous alumina exhibits good performance With excellent separation, adsorption and catalytic properties, it has broad application prospects in the fields of electronics, catalysis, biomedicine, ceramics and other fields. It is difficult to prepare mesoporous alumina, especially high-performance mesoporous alumina. However, with the continuous deepening of research and breakthroughs in preparation technology, the scale of mesoporous alumina industry will continue to expand.
