摘要:The present invention relates to a platinum (Pt)-molybdenum (Mo) catalyst for synthesis of hydrogen and a method of preparing hydrogen using same, the catalyst for synthesis of hydrogen according to the present invention comprising: a porous carrier; platinum carried in fine pores of the porous carrier; and molybdenum carried in mixture with the platinum in the fine pores. According to the present invention, hydrogen can be effectively obtained from a liquid organic hydrogen storage since dehydrogenation activity is significantly improved even at a low temperature by carrying platinum and molybdenum in a mixed state in the porous carrier.

摘要:An improved method for the synthesis of the anticancer drug picoplatin is provided. Condensation of a tetrachloroplatinate salt (TCP), such as potassium tetrachloroplatinate, and 2-picoline, in a solvent, is catalyzed by the presence of oxygen, such as in air, and additionally catalyzed by the presence of a Pt +4 complex, such as potassium hexachloroplatinate. The oxygen can be introduced into the reaction mixture by sparging, optionally with high shear mixing and under an inert gas headspace. The product trichloropicolineplatinate salt (TCPP) is a key intermediate in the synthesis of picoplatin, to which it can be converted by reaction of the TCPP with ammonia.

摘要:Selective gas-reducing methods for making shape-defined metal-based nanoparticles. By avoiding the use of solid or liquid reducing reagents, the gas reducing reagent can be used to make shape well-defined metal- and metal alloy-based nanoparticles without producing contaminates in solution. Therefore, the post-synthesis process including surface treatment become simple or unnecessary. Weak capping reagents can be used for preventing nanoparticles from aggregation, which makes the further removing the capping reagents easier. The selective gas-reducing technique represents a new concept for shape control of nanoparticles, which is based on the concepts of tuning the reducing rate of the different facets. This technique can be used to produce morphology-controlled nanoparticles from nanometer- to submicron- to micron-sized scale. The Pt-based nanoparticles show improved catalytic properties (e.g., activity and durability).

权利人:US NAVY
摘要:The present invention is a polyol method for making composite particles of two or more immiscible transition metals, where these particles are of nanoscale dimensions, and where the constituent metals are of essentially nanocrystalline morphology. The method of the invention has the steps of (1) dissolving or suspending two or more precursor metal compounds in an alcohol or polyol (diol, triol, etc.) solution, and (2) taking the solution or suspension to a temperature where the metal compound reduces, causing the first and second metals to form nanoscale composites. The term “polyol solutionâ€? will be used herein to describe solutions that contain either alcohol or polyol.

权利人:JIRO HIRAISHI DIRECTOR GENERAL
摘要:The present invention provides a process for synthesizing tertiary carboxylic acids or the esters thereof having one or two more carbon atoms than the raw material has, comprising reacting in a strong acid (e.g., sulfuric acid, sulfuric acid-phosphoric acid, hydrogen fluoride, fluorosulfuric acid, boron trifluoride.water complex and trifluoromethanesulfonic acid) a raw material compound (i.e., olefin, alcohol, diene, diol or saturated hydrocarbon) with carbon monoxide in the presence of a specific metal carbonyl catalyst (i.e., platinum carbonyl catalyst, palladium carbonyl catalyst and gold dicarbonyl catalyst). The metal carbonyl catalyst is formed by reacting in a strong acid at least one specific metal compounds (e.g., platinum compound such as platinum (II, IV) oxide, platinum (II, IV) hydroxide, a platinum powder, etc.; palladium compound such as palladium (II, III, IV) oxide, palladium (II) hydroxide, palladium (II) sulfate, palladium (II) carboxylate, a palladium powder, etc.; and gold compound such as gold (I, III) oxide, gold (I, III) hydroxide, a gold powder, etc.) with carbon monoxide.

摘要:Disclosed is a supported nanoparticle catalyst, methods of making the supported nanoparticle 5 catalysts and uses thereof. The supported nanoparticle catalyst includes catalytic metals M1, M2, M3, and a support material. M1 and M2 are different and are each selected from nickel (Ni), cobalt (Co), manganese (Mn), iron (Fe), copper (Cu) or zinc (Zn), wherein M1 and M2 are dispersed in the support material. M3 is a noble metal deposited on the surface of the nanoparticle catalyst and/or dispersed in the support material. The nanoparticle catalyst is 10 capable of producing hydrogen (H2) and carbon monoxide (CO) from methane (CH4) and carbon dioxide (CO2).
