Destruction of porous spherical Mo132 nanocluster polyoxometallate of keplerate type in aqueous solutions

Resumo

The mechanism and kinetics of the decomposition of the Mo₁₃₂ nanocluster polyoxomolybdate (POM) with a keplerate structure in aqueous solutions, including those containing calcium ions, were studied. The destruction mechanism of POM and the lifetime of Mo₁₃₂ depend on the initial concentration of its solutions, and this, in turn, is related to the thermodynamic factors. The destruction of keplerate can be described as an autocatalytic process. The calcium ions stabilize POM to different degrees depending on their content in solution.
