H3PW12O40 (PW12) was immobilized over mesoporous alumina through the reaction of mesoporous alumina functionalized 3-aminopropyl triethoxy silane (3-APTES) and PW12. The surface properties of the functionalized nanocomposite was analyzed by a series of characterization techniques like elemental analysis, FTIR and XRD. XRD and adsorption–desorption analysis shows that the mesostructure of silica...

Nanometric ions, such as polyoxometalates (POMs) or ionic boron clusters, with low charge density have previously shown a strong propensity to bind macrocycles and adsorb neutral surfaces: micellar, surfactant covered water–air polymer surfaces. These association phenomena were arise from solvent-mediated effect called the (super-)chaotropic effect. We show here by combining cloud point (CP) me...
