In this feature article we focus on the main developments in the area of ordered mesoporous materials (OMMs) since their discovery in 1992, which is considered one of the milestones in the history of porous materials. Nowadays, there are almost unlimited opportunities in the synthesis of composite- or modified OMMs by using soft- and hard-templating strategies and related methods. Nevertheless, there is still a great challenge to obtain diverse OMMs with well-developed porosity and desired morphology, crystallinity and surface properties. The evolution of the leading OMM members: silicas, organosilicas, metal oxides, carbons, metal-organic frameworks and zeolites, including the main factors affecting their development, is briefly summarized with special emphasis on the authors' accomplishments in this area. Additionally, recent advancements, challenges and prospects in the field of OMMs are presented. This feature article presents the main developments in the area of ordered mesoporous materials (OMMs) since their discovery in 1992, which is considered one of the milestones in the history of porous materials.
