    摘要: The present invention relates to a novel method for preparing a new type of catalyst for the oxidation of CO in a reactant gas or air. The method provides the preparation of a catalyst having nano-sized metal particles and a capping agent deposited on a solid support. The size and distribution of the metal particles can be easily controlled by adjusting reaction condition and the capping agent used. The catalyst prepared has high activity at low temperature toward selective oxidation of CO and is stable over an extended period of time. The catalyst can be used in air filter devices, hydrogen purification processes, automotive emission control devices (decomposition of NOx, x is the integer 1 or 2), F-T synthesis, preparation of fuel-cell electrode, photocatalysis and sensors.

    摘要: The inventors have discovered catalyst ignition promoters comprising one or more activated metals. The catalyst ignition promoters are easily prepared from a number of metal sources, including spent catalysts, are activated quickly and provide effective catalyst ignition independent of the quality of the metals that comprise the catalytic converter. The one or more activated metals comprising the ignition promoter are prepared by contacting them with one or more chemical treatments. The activated metal components are prepared into suitable articles, referred to as ignition strips, that are placed in contact with one or more oxidative coupling catalysts, typically in the form of gauzes. The ignition promoters reduce the activation energy for catalyst ignition (also referred to “light off”), enabling ignition of catalyst gauzes that are new, used, contaminated, damaged and combinations thereof at a relatively low auto-ignition temperatures.
