An electrochemical quartz crystal nanobalance was used to study the redox behavior of palladium phthalocyanine microcrystals attached to gold and platinum in aqueous solutions at different pH values. In order to investigate the substrate effect, paraffin impregnated graphite electrodes were also applied. It was found that the redox transformations of palladium phthalocyanine are accompanied with deprotonation-protonation as well as the sorption and desorption of counter-ions, the extent of which depend on the pH. Based on the results of the nanogravimetric measurements, a redox mechanism describing the pH dependence is suggested. Simultaneously with charge transfer processes, solid-solid phase transitions and water transport occur.
