Honeycomb Metal Substrate Metallic Substrate Catalyst

The components in a catalyst consist of two or more metals. Square Metal Catalyst For example, platinum-rhenium and other double (multiple) metal reforming catalysts supported on chlorine-containing gamma-alumina. They have better performance than the aforementioned platinum-only reforming catalysts, in which multiple metals supported on the carrier can form binary or multivariate clusters of metal atoms, so that the effective dispersion of the active component is greatly improved. Industrial Metal Catalytic Converter The concept of metal atom cluster compounds first came from the complex catalyst, applied to the solid Metal Catalyst, it can be considered that the metal surface also has several, dozens or more metal atoms gathered into clusters. Since the 1970s, based on this concept, a model of the active center of metal atomic clusters has been proposed to explain the mechanism of some reactions. In supported and unsupported polymetallic catalysts, if an alloy is formed between the metal components, it is called an alloy catalyst. The research and application of binary alloy catalysts are more, such as copper-nickel, copper-palladium, palladium-silver, palladium-gold, platinum-gold, platinum-copper, platinum-rhodium, etc. The activity of the catalyst can be adjusted by adjusting the composition of the alloy. The surface and phase composition of some alloy catalysts are obviously different. For example, when a small amount of copper is added to the nickel catalyst, the original surface structure of the nickel catalyst is changed due to the enrichment of copper on the surface, and the hydrocracking activity of ethane is rapidly reduced. Alloy catalysts have been used in hydrogenation, dehydrogenation and oxidation.
