摘要:
A supported bi-metallic non-platinum catalyst that is capable of oxidizing hydrazine to produce, as by-products of energy production, nitrogen, water, and zero or near-zero levels of ammonia is described. The catalyst is suitable for use in fuel cells, particularly those that utilizes an anion-exchange membrane and a liquid fuel such as hydrazine.

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:
Supercapacitive bioelectrical systems (SC-BESs) wherein the anode and cathode act as electrodes for a self-powered internal supercapacitor. The BES may further be enhanced by the use of optimized catalysts and enzymes to increase cell voltage and the use of a third capacitive electrode (AdE) short-circuited to the BES cathode and coupled to the BES anode to improve the power output of the self-powered internal supercapacitor.
摘要:
A method of preparing catalytic materials comprising depositing platinum or non-platinum group metals, or alloys thereof on a porous oxide support.
摘要:
According to various embodiment the present disclosure provides novel and inexpensive methods of forming amorphous silicon and silicon composite materials with specific pre-determined morphologies and oxygen contents. The various forms of amorphous silicon that result from these methods is useful in a wide variety of applications including, but not limited to, solar and lithium-ion batteries.
