Degradation of oxynitride based photoanodes.

ABSTRACT: The production of green hydrogen via photoelectrochemical water splitting has the potential to play a vital part in the decarbonization of our energy economy. To commercialize this technology, the stability of the current photoelectrode materials needs to be improved. Therefore, it is essential to understand the processes causing degradation and define suitable figures of merit. This work investigates the degradation mechanisms of oxynitride electrodes focusing on TiO₂ necked LaTiO₂N particle-based photoanodes. Their degradation behaviour was assessed by chronoamperometries at 1.23 V vs. RHE in basic electrolyte. We identified two current decay processes based on a semi-empirical correlation between the measured chronoamperometries and a sum of two expon
