SELECTIVE ELECTROCATALYTIC OXIDATION OF GLYCEROL ON BIMETALLIC ANODE CATALYSTS IN ANION EXCHANGE MEMBRANE FUEL CELLS

摘要

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 single AEMFC with non-PGM cathode and the self-prepared anode catalysts have demonstrated high output electrical power density.
