摘要： Variations of ZPGM bulk powder catalyst materials, including Cu—Co—Mn ternary spinel systems for TWC applications are disclosed. Bulk powder catalyst samples are prepared employing a plurality of molar ratio variations, including disclosed Cu—Co—Mn spinel on Praseodymium-Zirconia support oxide made by incipient wetness method, or Cu—Co—Mn spinel on Niobium-Zirconia support oxide, which may be synthesized by co-precipitation method. A plurality of bulk powder catalyst samples may be tested by performing isothermal steady state sweep test, employing a flow reactor at inlet temperature of about 450° C., and testing a gas stream from lean to rich condition and influence on TWC performance measured/analyzed, which may lead into significant improvements in the manufacturing of ZPGM bulk powder catalyst materials for TWC applications.

摘要： Variations of bulk powder catalyst material including Cu—Co, Fe—Co, and Co—Mn spinel systems for ZPGM TWC applications are disclosed. The disclosed bulk powder catalyst samples include stoichiometric and non-stoichiometric Cu—Co, Fe—Co, and Co—Mn spinels on Pr6O11—ZrO2 support oxide, prepared using incipient wetness method. Activity measurements under isothermal steady state sweep test condition may be performed rich to lean condition. Catalytic activity of bulk powder samples may be compared to analyze the influence that different bimetallic spinel compositions may have on TWC performance, including ZPGM materials for a plurality of TWC applications. Stoichiometric Cu—Co, Fe—Co, and Co—Mn spinel systems exhibit higher catalytic activity than non-stoichiometric Cu—Co, Fe—Co, and Co—Mn spinel systems. The influence of stoichiometric Cu—Co, Fe—Co, and Co—Mn spinel systems may lead into cost effective manufacturing solutions for ZPGM TWC systems.
