Inversely polarized thermo-electrochemical power generation via the reaction of an organic redox couple on a TiO₂/Ti mesh electrode.

ABSTRACT: We demonstrate thermo-electrochemical (TEC) conversion using a biocompatible redox couple of lactic acid and pyruvic acid on earth-abundant TiO₂. The TEC cell exhibited a positive Seebeck coefficient of 1.40 mV K^-1. DFT calculations figured out that the adsorption of intermediate species and protons on TiO₂ controls both the redox reaction and current polarity.
