The accelerated degradation tests (ADTs) were performed
in a setup already described as a part of our previous work.10 (link),48 (link),54 (link) Briefly, the setup was composed
of a two-compartment HT cell using 0.1 M HClO4 electrolyte
(Carl Roth, Rotipuran Supra) with a conventional three-electrode system
controlled by a potentiostat (SP-200 Potentiostat, Biologic). A reversible
hydrogen electrode (HydroFlex) was used as a reference (separated
from the working electrode in a different compartment via a salt bridge),
and a graphite rod was used as a counter electrode. To prevent evaporation
of the electrolyte due to prolonged ADTs at high temperature (60 °C),
in addition to the condenser, the other open parts of the HT-DE cell
(the capillary for the counter electrode, the capillary for the salt
bridge, and the beaker for the reference electrode) were covered by
the in-house designed PEEK caps.
