Catalysis of indium ion electroreduction in the presence of acetazolamide in chlorates(VII) solutions with varied water activity

Chemphyschem. 2024 Feb 16:e202300789. doi: 10.1002/cphc.202300789. Online ahead of print.ABSTRACTThe influence of acetazolamide (ACT) on the kinetics and the mechanism of electroreduction of In(III) ions as a function of changes of the water activity was investigated using electrochemical methods (DC, SWV, CV and EIS, CV). The multi-step mechanism of the electroreduction process should take into account the dehydration step of indium ions and the presence of In - ACT (,,cap-pair" effect) active complexes, mediating electron transfer, located in the adsorption layer. Differences in the electrode mechanism in the presence of ACT were observed for higher chlorates(VII) concentrations (above 4 mol‧dm-3 chlorates(VII)) reflected by a lack of step wise nature of the electrode process. The highest catalytic activity was observed in 4 mol·dm-3 chlorates(VII).PMID:38363084 | DOI:10.1002/cphc.202300789
