by the use of noble metal catalysts (I-7), and to date the normal substrate for these catalysts has been a porous ceramic, either in pelleted or cellular monolith form. In general the ceramic monolith has gained greater accept- ance in high-flow velocity operation due to the low pressure drop inherent in its con- .   Cordierite honeycomb catalysts supported on rare earth (RE)-transition metal oxides, used for removing simultaneously three major pollutants, carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxides (NOx), in automotive emission have been investigated. The results indicate that the catalyst has improved three-way performance (TWP).Cited by: 7. Effect of support oxide and noble metal precursor on the activity of automotive diesel catalysts.

Copper-cerium mixed oxide catalysts have gained ground over the years in the field of heterogeneous catalysis and especially in CO oxidation reaction due to their remarkable performance. In this study, a series of highly active, atomically dispersed copper-ceria nanocatalysts were synthesized via appropriate tuning of a novel hydrothermal method.

Base metal catalysts are commonly used for steam reforming of hydrocarbons, and Ni-based catalysts in particular have been found to be effective for tar and methane removal in biomass gasification. In addition, in the presence of steam and/or oxygen, nickel can be used to.   Development of Non-Noble Metal Catalysts for the Purification of Automotive Exhaust Gas (Lin Peiyan et al.).

Noble-Metal Catalysts Noble-metal catalysts such as Pt or Au are the most common oxidation catalysts. This is due to their high selectivity to oxidation reactions. The main drawback with these noble-metal catalysts is the cost. This is why the interest of new catalysts that are not based on noble-metals is increasing. [6] Non-Noble-Metal Catalysts. Among the factors affecting chemical reaction rates discussed earlier in this chapter was the presence of a catalyst, a substance that can increase the reaction rate without being consumed in the concepts introduced in the previous section on reaction mechanisms provide the basis for understanding how catalysts are able to accomplish this very important function.
