Abstract

Glycerol is a co-product from Biodiesel production with high abundance and low market price. Its transformation into valuable products or its use as an alternative source of energy has driven the search for selective catalysts. Herein we show first findings of perovskites as electrocatalysts for glycerol electrooxidation reaction (GEOR). Alternatively to Pt and Pd based catalyst, perovskite oxides (LaNiO3 and LaCoO3) demonstrated high catalytic performance with faradaic currents of ca. 18 mA mg-1 at potentials higher than 1.6 V vs. RHE. LaCoO3 exhibited resistance to poisoning during GEOR. Based on in situ FTIR and online HPLC experiments, GEOR on these perovskites yields formate and glycolate as final products, with no evidence of CO2 formation. Our results indicate that perovskites can be considered as alternative electrocatalysts for the selective oxidation of glycerol, opening the door for a new class of catalysts for polyols oxidation with efficiency in terms of current densities and poisoning resistance.
