标题:Synthesis of uniform diamond nanoparticles
发明人：YAN HAO; LYU TENGTENG
权利人:UNIV NORTH TEXAS
摘要:The synthesis of sub-five-nanometer nanodiamonds with high uniformity and purity. Inspired by the formation of natural diamond, iron carbide nanoparticles embedded in iron oxide matrices as the carbon source were used. High-pressure-high-temperature treatment of the precursor yields nanodiamonds with tunable diameters down to 2.13 nm and 0.22-nm standard deviation. The disclosed synthesis procedures also include a method for forming fluorescent nanodiamonds.

标 题:Catalyst for the synthesis of methanol
发明人：DIENES EDWARD K; COLEMAN RAY L; HAUSBERGER ARTHUR L
权利人:UNITED CATALYSTS INC
摘要:A methanol synthesis catalyst which comprises a major portion by weight of the oxides of copper and zinc and a minor portion by weight of a thermal stabilizing metal oxide is useful for the synthesis of methanol from the oxides of carbon and hydrogen at relatively low temperatures. The catalyst is characterized in that the ratio of copper oxide to zinc oxide, each expressed as a metal by weight, is in the range of from 2:1 to 3.5:1 and by the intimate association with each other of copper and zinc oxides and with said thermal stabilizing oxide. Further, the catalyst is characterized in that the amount of iron oxides, as an impurity, is less than 150 parts per million.

摘要:An object of the present invention is to offer a catalyst for the hydrogenation which is suitable for the synthesis of methanol from CO and/or CO 2 under the condition of low temperature and low pressure. In the said catalyst, Pd having a particle size of 5 nm or less is carried on a cerium type oxide (CeO 2 ) whereby methanol is synthesized by the reaction of CO and/or CO 2 with hydrogen. The said catalyst for the hydrogenation can be manufactured by a method where the catalyst is manufactured from a coprecipitate of a precursor of cerium type oxide and palladium and a method where palladium is separated in a cerium type oxide.
