Cathode catalysts for fuel cell application derived from polymer precursors
Patent
·
OSTI ID:1531960
A method of preparing M-N—C catalysts utilizing a sacrificial support approach and inexpensive and readily available polymer precursors as the source of nitrogen and carbon is disclosed. Exemplary polymer precursors include those that do not form complexes with iron, but which do complex with silica, for example, polyetheleneimine (PEI), Poly(2-ethyl-2-oxazoline), Poly(acrylamide-co-diallyldimethylammonium chloride), Poly(melamine-co-formaldehyde), Poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-s-triazine-2,4-diyl]-[(2,2,6,6-tetramethyl-4-piperidyl)imino]-hexamethylene-[(2,2,6,6-tetramethyl-4-piperidyl)imino] and the like.
