Hydrothermal Green Synthesis of LaO x ‐Modified Pt/C Catalyst for Glycerol‐to‐Glycerate Electrooxidation in Alkaline Medium

Abstract: Using the bromide anion exchange (BAE) green method to obtain carbon‐supported nanoparticles, Pt (LaO x)/C was successfully prepared under mild conditions. This material, containing LaO x species generated in situ during the synthesis, was efficiently used as an anode to perform glycerol oxidation in alkaline medium in batch mode and at room temperature. In a direct alcohol fuel cell (DAFC), this catalyst was able to boost the glycerol‐to‐glycerate conversion with a 49% selectivity and a 28% power density higher than the same system using a BAE‐synthesized Pt/C anode. The increase in catalytic activity may be due to the interaction of LaO x with the Pt active sites, acting as a bifunctional electrode. Furthermore, when used as an anode in an electrolysis setup, the selectivity of glycerol toward glycerate increased up to 67%. In situ FTIR and HPLC analyses confirmed the formation of the value‐added glycerol oxidation products.
