A method of preparing M-N&#x2014;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 non-porphyrin precursors with no initial catalytic activity. Examples of suitable non-catalytic non-porphyrin precursors include, but are not necessarily limited to low molecular weight precursors that form complexes with iron such as 4-aminoantipirine, phenylenediamine, hydroxysuccinimide, ethanolamine, and the like.

Non-PGM cathode catalysts for fuel cell application derived from heat treated heteroatomic amines precursors

A method of preparation of metal-chalcogen-nitrogen-carbon (M-Ch-N&#x2014;C) catalytic material utilizing a sacrificial support approach and using inexpensive and readily available precursors is described. Furthermore, the catalytic materials synthesized using the disclosed methods include multiple types of active sites.

Cathode catalysts for fuel cells

A method of preparing M-N&#x2014;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.

Cathode catalysts for fuel cell application derived from polymer precursors

A method of determining individual velocity associated with one or more molecular species moving through a fluid medium involves obtaining multiple temporal images of the one or more species moving through the medium, analyzing the temporal images using multivariate image analysis to obtain temporal profiles of principal components, and determining individual velocity of the one or more species using the temporal profiles. Multiple species can be identified using the one or more individual velocities or ratio thereof.
