Mesoporous Tungsten Trioxide Application

Applications In The Field Of Catalysts
Mesoporous molecular sieve has a high specific surface area , pore structure and orderly rules, which is an excellent catalyst carrier. Solid heteropolyacid is a new type of catalytic materials with properties superacids; it is not only friendly to environment, but also possesses the advantages of high activity. In practice, it can be supported on a suitable carrier. Mesoporous materials is larger pore diameter which is good for acid anion achieves sufficiently into the role and plays the role of dispersion The tungsten trioxide (wo3) supported on niobium oxide (Nb2O5) and alumina (Al2O3), the availability of tungsten trioxide in the niobium oxide has better dispersibility. It is more likely to be restored for tungsten trioxide with solid solution. Compared with wo3 / Al2O3 catalyst, the reactions have higher activity because wo3 / Nb2O5 oxidation .

Applications In The Field Of Adsorption
Mesoporous materials have a unique application in the field of separation and adsorption. It not only has a high adsorption capacity to nitrogen, but also can recycle all kinds of volatile organic compounds and other heavy metals. The synthesis materials of hexagonal mesoporous can absorb elements in nuclear waste, which can achieve better results.

Currently, the research of mesoporous materials tungsten trioxide faces with larger difficulties, mainly because of its complex preparation valences, there are many worthy of study and problems need to be resolved.
