Abstract

Three-dimensional (3D) ordered cubic mesoporous Co-Mn oxide (denoted as CoMn-HT) was fabricated using a KIT-6-templating strategy and was tested in a "storage-oxidation" cycling process for the removal of formaldehyde. The formation of a 3D ordered mesoporous structure was confirmed by low-angle XRD, nitrogen adsorption-desorption data, and TEM micrographs. The CoMn-HT catalyst showed promising properties in both the storage and regeneration phases, and remained active in highly humid air (RH = 90%) and at high GHSV (160,000 h- 1). The excellent catalytic performance of CoMn-HT was associated with its large surface area and 3D ordered mesoporous structure.
