摘要:
A variety of inorganic-organic hybrid materials and various methods for preparing and using the same are described. The hybrid materials are graphene or graphitic materials populated with organic molecules and may have a variety of surface defects, pits or three-dimensional architecture, thereby increasing the surface area of the material. The hybrid materials may take the form of three dimensional graphene nanosheets (3D GNS). If the organic molecules are enantiospecific molecules, the hybrid materials can be used for chiral separation of racemic mixtures.
摘要:
Platinum or platinum group metal decorated non-oxide materials that are formed using a synthesis pathway that avoids the production of intermediate oxides. The materials are suitable for use as catalysts and may or may not be porous.
摘要:
A porous metal-oxide composite particle suitable for use as a oxygen reduction reaction or oxygen evolution reaction catalyst and sacrificial support based methods for making the same.
摘要:
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.
摘要:
