Abstract:

The sorption of acetone from the vapor phase by Keplerate polyoxomolybdate (POM) nanoclusters, Mo-132 and Mo72Fe30, and Mo-138, a POM with a toroid structure, is studied via equilibrium interval sorption (a modification of vapor sorption gravimetry). The highest sorption capacity is registered for Mo-132, while the other two show performance an order of magnitude lower. The specific Gibbs energy of the interaction between the POMs and acetone is reported. Small-angle X-ray and neutron scattering analysis indicates a considerable difference between the natures of Mo-132 and Mo-138 surfaces.
