Synthesis of Diatomite-Based Mesoporous Wool-Ball-Like Microspheres and Their Application for Toluene Total Oxidation Reaction

Diatomite (DE) has attracted considerable attention owing to its abundance, low cost, and potential for a wide variety of applications.This work reports the development of mesoporous wool-ball-like (WBL) microspheres from natural DE through a simple hydrothermal treatment.We discovered that the presence of cetyltrimethylammonium bromide is a PPE Supplies prerequisite for generating monodispersed WBL microspheres.

The mechanism for the transformation of pristine DE into mesoporous microspheres through dissolution−recrystallization was clearly investigated.Interestingly, the microspheres exhibited a specific surface area 25−60 times larger Makeup Bag than that of the pristine DE.The application of WBL microsphere DE as an effective support for metallic catalysts in the toluene total oxidation reaction was demonstrated.
