摘要： It has been discovered that catalysts may be modified by depositing an agent derivative from an agent such as an organometallic compound upon them. Such a modification gives a catalyst useful in increased selectivity to para-substituted alkyl benzenes, such as para-xylene (PX), through reacting an aromatic compound such as toluene and/or benzene with a methylating agent from hydrogen and carbon monoxide and/or carbon dioxide and/or methanol. Using these selectivated catalysts, para-substituted alkyl benzenes can be recovered in a selectivity of 80% or greater, significantly better than the equilibrium concentration of 24%.

摘要： The present invention discloses a method of synthesizing single walled carbon nanotubes. Highly pure single walled carbon nanotubes is synthesized by the catalytic decomposition of carbon containing gases with Fe, Co, Ni, Mo and W catalysts in the presence of a small mount of water vapor, which can prohibit the generation of amorphous carbon and multi-walled carbon nanotubes on the surface of the catalysts and promote the generation of single-walled carbon nanotubes.

摘要： A support for a catalyst for controlling vehicular exhaust emissions comprising a high surface area refractory metal oxide, e.g., gamma-alumina, having a monomolecular layer of a second oxide selected from the group consisting of titanium dioxide, cerium dioxide and zirconium dioxide. Typically, the monomolecular layer will have a thickness of less than about 10 angstroms. The support may be converted into a vehicular exhaust emission control catalyst by depositing the support on a substrate such as cordierite depositing a precious metal component such as platinum on at least part of the monomolecular layer. Preferably, the catalyst will also contain at least one NOx storage component deposited on at least part of the monomolecular layer. Catalysts prepared using the catalyst supports of the invention exhibit outstanding thermal stability and resistance to sulfur poisoning.
