摘要: The invention relates to a process and to an apparatus for preparing a heterogeneous catalyst having at least one catalytically active species bound to the surface of a support material. According to the process, the surface of the support is first pretreated. A catalyst reagent containing the catalytically active species or its precursor is vaporized and the vapor is routed into a reaction chamber where it is brought to interact with the support material. The catalyst reagent not bound to the support is withdrawn from the reaction chamber in gaseous form. If necessary, the species bound to the support is posttreated in order to convert it into a catalytically active form. According to the invention, the amount of catalyst reagent brought into the reaction chamber is at least equal to, preferably in excess of the number of available binding sites on the surface. The temperature of the support of kept higher than the condensation temperature of the vapor and at the same time at a sufficiently high level to attain the thermal activation energy needed for forming bonds between the active species and the support. By binding the catalytically active species in this way to the support it is possible to provide a heterogeneous catalyst having a high activity even at small amounts of the active species.

摘要: The present invention concerns a method for preparing heterogeneous catalysts. According to the method, preparation is carried out under such process conditions in which the bonding of compounds from the gas phase onto the surface of a support material is primarily determined by the properties of the support surface. The constituents contained in the reagent are then selectively bonded to the bonding sites of the support material surface, thus forming stable surface bonds. According to the invention, the number of surface-bond sites available for preparing a stable product with surface bonds is controlled by varying the reaction temperature and/or selecting a suitable reagent. The invention makes it possible to control the metal content of the end product at a predetermined level.

摘要: The invention relates to a method and apparatus for growing a thin film onto a substrate, in which method a substrate placed in a reaction space (21) is subjected to alternately repeated surface reactions of at least two vapor-phase reactants for the purpose of forming a thin film. According to the method, said reactants are fed in the form of vapor-phase pulses repeatedly and alternately, each reactant separately from its own source, into said reaction space (21), and said vapor-phase reactants are brought to react with the surface of the substrate for the purpose of forming a solid-state thin film compound on said substrate. According to the invention, the gas volume of said reaction space is evacuated by means of a vacuum pump essentially totally between two successive vapor-phase reactant pulses. By virtue of transporting the different starting material species at different times through the apparatus effectively isolates the starting materials from each other thus preventing their premature mutual reactions.

摘要: The invention relates to equipment for growing a thin film onto a substrate. The equipment suited to implement the invention comprises a reaction space having a reaction chamber therein into which a substrate is placed and is subjected to alternately repeated surface reactions of at least two vapor-phase reactants for the purpose of forming a thin film. The equipment further comprises recesses/openings communicating with the reaction space to form gas inflow and outflow channels. The reactants are fed in the form of vapor-phase pulses repeatedly and alternately into the reaction space through the inflow channels, each reactant separately from its own source. The vapor-phase reactants are brought to react with the surface of the substrate for the purpose of forming a solid-state thin film compound on said substrate. The gaseous reaction products and possible excess reactants are removed in gas phase from the reaction space via the outflow channels.

摘要: A method for growing a thin film on a substrate. A substrate is placed in a reaction space. The substrate is subjected to at least two vapor phase reactants in the form of vapor phase pulses, repeatedly and alternately. Gas within the reaction space is purged between two successive vapor phase pulses essentially entirely by use of a pump connected to the reaction space. The reaction space is purged between two successive vapor phase pulses such that less than 1% of the residual components from the first vapor phase pulse remains prior to the inflow of the second vapor phase pulse.
