Preparation of MCM-41 incorporated with lacunary Keggin polyoxometalate and its catalytic performance in esterification

Study of the esterification reaction of acetic acid with n -butanol over supported WO 3 catalysts

“…5. It is noteworthy that the conversions of the best supported WO 3 catalysts in this series were higher than those of other systems in the literature over the same amount of time [21][22][23][24], including commercially available solid acid catalysts [25].…”

Restructuring of silica-pillared clay (SPC) through posthydrothermal treatment and application as phosphotungstic acid supports for cyclohexene oxidation

“…When 1.0 g SPC-AT-2 loading is about 0.2 g HPW, some characteristic peaks of HPW crystal are very clearly to be observed in the wide-angle XRD pattern (see S5). Although the broad nature of the XRD patterns can be ascribed to the ultrasmall size of HPW crystalline [43][44][45], the crystalline size is much bigger than SPC-AT-4 does.…”

A ‘build-bottle-around-ship’ method to encapsulate ammonium molybdophosphate in zeolite Y. An efficient adsorbent for cesium

“…However, the bulk AMP has not been widely explored in cesium adsorption because of their microcrystalline form leads to low flow rates and clogging in flow through applications [9,10]. Dispersion of AMP on various supports, such as ion-exchange resin [11], organic polymer [12], titanium silicate [13], and mesoporous silica [14][15][16] is one way to solve this problem.…”
