摘要:The invention provides methods for a one-pot synthesis of molecular sieves of the CHA-type. The method uses molecular and non-molecular sieves as sources of silicon and aluminum. A first OSDA is selected from tetraethylenepentamine (TEPA) and triethy-lenepentamine (TETA). The synthesis mixture comprises a first metal selected from copper, iron and zinc. Optionally, the synthesis mixture may furthermore comprise a second OSDA and/or a second metal selected from manganese, cesium, magnesium, calcium, strontium, barium, yttrium, titanium, zirconium, niobium, iron, zinc, silver, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and mixtures thereof. The molecular sieves of the CHA-type obtainable by the method can be used as SCR-catalytically active substances for the removal of nitrogen oxides from exhaust gases of combustion engines.

摘要:The invention relates to methods for producing primary, secondary and tertiary amines and corresponding enantiopure or enantioenriched primary or secondary amine products, comprising the steps of reductively aminating a ketone, with a nitrogen auxiliary in the presence of a hydrogenating catalyst and a hydrogenating agent, wherein the reductive animation is performed under the influence of a mild Lewis acid, the mild Lewis acid being present at the onset of the reductive amination in at most 25 mol% of the ketone or the nitrogen auxiliary.

摘要:Methods are described for making a texturized catalyst. The textural promoter may be a high-surface area, high-porosity, stable metal oxide support. The catalyst is manufactured by reacting catalyst precursor materials and support materials in a single, solvent deficient reaction to form a catalyst. The catalyst may be particles or a coating or partial coating of a support surface.

摘要:The present invention relates to a nanophosphor which may be used as a wavelength conversion part of a solar cell, a fluorescent contrast agent, and a light emitting part of a display device, and a synthesis method thereof. The nanophosphor of the present invention is excited by ultraviolet light to exhibit strong green light emission, and has multicolor light emission characteristics capable of controlling a color such as green, yellowish green, yellow, and orange color by only adjusting the amount of a doping agent.
