FT-IR in situ thermoelectrochemical cell for electrode kinetics study

The main parameter, that determines the use of thermoelectrochemical converters (TECC) for the waste heat harvesting is the efficiency of thermoelectric conversion. An increase of the current density at the electrode is possible due to the use of heterogeneous redox catalysts. In this paper, early results of Ti-based mineral catalysts usage are presented. A new type of thermoelectrochemical cell for in situ FTIR spectroscopy was designed, assembled and tested. With its use, the pattern of the redox reaction in K 3 [ F e ( C N ) 6 ] ↔ K 4 [ F e ( C N ) 6 ] conversion was confirmed.
