Glycerol will be massively obtained as a byproduct of blooming biodiesel production, therefore, it has potential to serve as a main building block molecule for future productions of higher-valued oxygenated chemicals. We will present our recent research on selective oxidation of glycerol on precious metal � transitional metal bimetallic anode catalysts in anion exchange membrane fuel cells (AEMFCs). A solution phase reduction method was developed to prepare Pt, Pd, Au and their bimetallic catalysts, such as PtNi, PtCo, PtV, PtFe nanoparticles, PtFe, PdFe-nanowires (NW) with small diameter of 2-5 nm. The fuel cell operation voltage (anode overpotential) was found to be able to regulate the oxidation product distributions. PtM bimetallic catalysts favors production of glyceric acid with high selectivity. The detailed oxidation mechanistic steps in high pH media will be presented.
