Mesoporous Metal Oxides

Abstract

Mesoporous metal oxides, which combine the high specific surface area of mesoporous materials with the abundant physicochemical properties of metal elements, have shown significant potential in various fields. However, the development of effective methods for the synthesis of mesoporous metal oxide materials has faced numerous challenges, including rapid hydrolysis of metal precursors, difficulties in synthesis process control, and premature crystallization before mesoporous micelles can coassemble. This Review provides a systematic overview of the current synthesis methodologies for mesoporous metal oxide materials, focusing on two key dimensions: mesopore construction (including hard template, soft template, and template-free methods) and skeleton formation (such as the EISA method, the sol−gel method, and the grinding method). Additionally, this Review offers a detailed classification of mesoporous metal oxide materials based on their components. The current major challenges, along with an outlook on future developments in the synthesis methodologies for mesoporous metal oxides, are discussed.
