摘要： Ceramic catalytic compositions, systems, and methods for oxidizing, converting and/or removing NO X gas species present in gas streams such as exhaust gases are provided. The catalysts of the invention oxidize the nitrogen monoxide (NO) in gas streams to nitrogen dioxide (NO 2 ), which may be adsorbed by a metal oxide or other NO 2 adsorber. Catalysts suitable for use in systems of the present invention include ceramic oxides, mixtures of ceramic oxides, complex ceramic oxides, and mixtures of complex ceramic oxides. Such catalysts are shown herein to successfully achieve an NO-NO 2 equilibrium gas composition at temperatures as low as 275°C. In addition, by using the catalyst with an NO 2 adsorber, greater than 95% removal of combined NO and NO 2 from the gas stream has been successfully demonstrated. Further, specific strategies have been identified to regenerate the catalyst system and restore performance after prolonged exposure to species such as sulfur dioxide (SO 2 ).

摘要： A metal-air battery is disclosed in one embodiment of the invention as including a cathode to reduce oxygen molecules and an alkali-metal-containing anode to oxidize the alkali metal (e.g., Li, Na, and K) contained therein to produce alkali-metal ions. An aqueous catholyte is placed in ionic communication with the cathode to store reaction products generated by reacting the alkali-metal ions with the oxygen containing anions. These reaction products are stored as solutes dissolved in the aqueous catholyte. An ion-selective membrane is interposed between the alkali-metal containing anode and the aqueous catholyte. The ion-selective membrane is designed to be conductive to the alkali-metal ions while being impermeable to the aqueous catholyte.

摘要： An electrolytic cell produces coupled radical products. The method involves obtaining a carboxylic acid material from biomass and converting it into an alkali metal salt. The alkali metal salt is then used in an anolyte as part of an electrolytic cell. The electrolytic cell may include an alkali ion conducting membrane (such as a NaSICON membrane). When the cell is operated, the alkali metal salt of the carboxylic acid decarboxylates and forms radicals. Such radicals are then bonded to other radicals, thereby producing a coupled radical product such as a hydrocarbon. The produced hydrocarbon may be, for example, saturated, unsaturated, branched, or unbranched, depending upon the starting material.
