Specifically, a method is described for preparing alkylhalogenosilanes by reacting, in a fluidized bed reactor, and alkyl halogenide, preferably CH3Cl, with a solid body, which is referred to as a contact body and which includes powdered silicon and a catalytic system including at least one copper catalyst and β1 and β2 promoter activities.
专利号:US-6281378-B1 优先权日:1995-06-08 标 题 :Vanadium-containing catalysts, process for manufacturing and use of the same 发明人:KISHIMOTO NOBUJI; MATSUNAMI ETSUSHIGE 权利人:NIPPON CATALYTIC CHEM IND 摘要:Vanadium-containing catalysts are obtained by using polyvanadic acid as a source of vanadium. Vanadium-containing catalysts are obtained by mixing catalyst components other than vanadium, or their precursors, with a polyvanadic acid sol which is formed by ion-exchanging a metavanadic acid aqueous solution with a proton-type cation-exchange resin and performing polycondensation, and by drying and/or calcining the mixture. Such vanadium-containing catalysts can fully exhibit their catalytic activity under mild reaction conditions, and can be suitably used for various reactions, such as synthesis of phthalic anhydride by the partial oxidation of o-xylene, synthesis of benzaldehyde by the partial oxidation of toluene, synthesis of benzoic acid by the partial oxidation of toluene, synthesis of anisaldehyde by the partial oxidation of p-methoxy toluene, synthesis of propylene by the oxidative dehydrogenation of propane, synthesis of isobutene by the oxidative dehydrogenation of isobutane, synthesis of methyl formate by the oxidative dehydrogenation of methanol, and synthesis of acrylonitrile by the ammoxidation of propane.

The resulting flakes can comprise nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances.

The resulting flakes can be C-containing anatase-based layers that are in turn comprised of nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances. Electrodes made from these materials performed well in energy systems. The materials also reduce the viability of some cancer cells. Also provided are mesoporous materials, devices, and related methods.
