In this work, different approaches for the direct and indirect electrooxidation of glycerol, a by-product of oleochemistry and biodiesel production, for the synthesis of value-added products and of intermediates for biofuel/electrofuel production, are investigated and compared. For the direct electrooxidation, metallic catalysts are used, whose surfaces are modified by promoters or second catalysts. Bi modified Pt electrodes (Pt x Bi y /C) serve as model systems for promoter-supported electrocatalysis, whereas IrO 2 -modified RuO 2 electrodes (DSA) are studied as catalyst combinations, which are compared under acidic conditions with the respective monometallic catalysts (Pt/C, RuO 2 /Ti, IrO 2 /Ti).
