Mass and charge transfer in systems containing nanocluster molybdenum polyoxometallates with a fullerene structure

Abstract

The sorption capacity of polyoxometallates with a buckyball structure (fullerene)

$$ (NH_4 )_{42} [Mo_{72}^{VI} Mo_{60}^V O_{372} (H_3 CCOO)_{30} (H_0 O)_{72} ] \cdot 30H_3 CCOONH_4 \cdot 250H_2 O $$

and

$$ (NH_4 )_{42} [Mo_{72}^{VI} Mo_{60}^V O_{372} (ClCH_2 COO)_{30} (H_2 O)_{72} ] \cdot 250H_2 O \cdot 15ClCH_2 COONa $$

with respect to organic substances and nitrogen was studied. The alcohol molecules were found to have at least two types of bond with the sorbent. Some of the molecules evaporate in air, while the rest are held more tightly. It was suggested that the adsorption involved both the outer and inner spheres of buckyballs and that the chemical interaction of the sorbate and sorbent contributed significantly to the process. It was established that the sorption largely depended on the nature of the stabilizing ligands of buckyballs. The parameters of the electrical transfer of the buckyball anions in water solutions were measured; the electric mobility, the transfer number, and the diffusion coefficient were determined.
