Non-conductive TiO2 as the anode catalyst support for PEM water electrolysis

Popis výsledku v původním jazyce

The applicability of a non-conductive TiO2 as the support of the anodic catalyst for PEM water electrolysis was tested. Three TiO2 samples with different specific surface areas were modified by IrO2 using a modified version of the Adams fusion method. Aconstant weight ratio of IrO2/TiO2 of 0.6 was maintained in all cases. The size, specific surface area and morphology of IrO2 electrocatalyst crystallites were investigated by X-ray diffraction, nitrogen adsorption (BET) and scanning electron microscopy,respectively. The electron conductivity of compressed catalyst powders was evaluated. Their electrochemical properties were studied on a rotating disk electrode (RDE) and finally in a laboratory electrolyser. Utilization of the TiO2 support resulted ina reduction in the size of the IrO2 crystallites. It was found that the lower the specific surface area of the supports, the higher was the electrochemical activity of the catalyst. This is most likely due to the formation of a conductive
