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 Mo<sub>132</sub> 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.</p></abstract><trans-abstract xml:lang="ru"><p>При термодеструкции нанокластерного полиоксометаллата (ПОМ) Mo<sub>132</sub> кеплератного типа в твердом состоянии в образцах возникали электрические заряды за счет выхода в окружающую среду амфифильных ионизированных молекулярных частиц. Разность потенциалов образец – земля достигала 100 и более вольт, знак заряда определялся наличием или отсутствием воздействия умеренного электромагнитного поля. В ходе изучения фотодеструкции ПОМ Mo<sub>132</sub> в водных растворах наблюдали такое электрохимическое явление, как возникновение фотогальванической разности потенциалов между электродами, помещенными в раствор сверху и снизу. Обнаружены также колебания величины разности потенциалов за счет процессов поляризации/деполяризации приэлектродных зон, обусловленных различной скоростью диффузии противоионов из верхней и нижней части раствора.</p></trans-abstract><kwd-group xml:lang="en"><kwd>nanocluster polyoxometallate</kwd><kwd>electrochemical phenomena</kwd><kwd>thermodestruction</kwd><kwd>solutions</kwd><kwd>oxidative photodestruction</kwd><kwd>fluctuation processes</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нанокластерный полиоксометаллат</kwd><kwd>электрохимические явления</kwd><kwd>термодеструкция</kwd><kwd>растворы</kwd><kwd>окислительная фотодеструкция</kwd><kwd>колебательные процессы</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>075-03-2023-006</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Pope M.T.
