Some electrochemical phenomena accompanying destruction of nanocluster polyoxomolybdate Mo<sub>132</sub>

During thermodestruction of keplerate-type nanocluster polyoxometallate (POM) Mo132 in the solid state, there were electric charges in the samples due to the release of amphiphilic ionized molecular particles into the environment. The sample-ground potential difference reached 100 and more volts, and the sign of the charge was determined by the presence or absence of the moderate electromagnetic field. In the course of studying the photodegradation of POM Mo132 in aqueous solutions, an electrochemical phenomenon such as the occurrence of photovoltaic potential difference between the electrodes placed in the solution from the top and bottom is observed. The fluctuations of the potential difference due to the processes of polarization/depolarization of the near-electrode zones caused by different diffusion rates of counterions from the upper and lower parts of the solution are also found.
