摘要: A composition and method for producing the same are provided. The composition includes transition metal oxides adhered to a surface of a cerium oxide support, and can additionally include alkali metal or alkaline earth metal promotors. The method includes incipient wetness impregnation of the support with metal salt in solution, and can include impregnation with a metal chelator salt. The composition can be useful as a catalyst for the reduction of noxious gases in combustion exhaust streams. The composition can be of particular use as a component of an automobile catalytic converter, for the specific catalytic reduction of nitrogen oxides to nitrogen gas.

摘要: A metal-gas battery that utilizes an exhaust gas stream from a combustion engine as reactive gases is provided. Almost constant concentration of exhaust gases are supplied to the metal-gas battery via an existing engine systematic combustion system. The systematic combustion system keeps a definite air fuel mixture (A/F) that acts to enhance the fuel efficiency of the vehicle, and the metal-gas battery leverages the existing vehicle air management system. Exhaust heat of the exhaust gases is sometimes utilized for the heat control of the vehicle, and then the cooled exhaust gases are introduced into the metal-air battery to be consumed during a cathode reduction reaction to create and store electrical energy. The metal-gas battery supports the cleaning of exhausted gases using existing emission catalysts.
