专利号:US-11964260-B2 优先权日:2016-08-08 标题:Method for manufacturing ammonia synthesis catalyst, and method for manufacturing ammonia 发明人:HOSONO HIDEO; KITANO MASAAKI; YOKOYAMA TOSHIHARU; LI JIANG; KAWAMURA SHIGEKI; KISHIDA Kazuhisa 权利人:TOKYO INST TECH; TSUBAME BHB CO LTD 摘要:Provided is a method for manufacturing a catalyst with which it is possible to obtain a supported metal ammonia synthesis catalyst, in which there are restrictions in terms of producing method and producing facility, and particularly large restrictions for industrial-scale producing, in a more simple manner and so that the obtained catalyst has a high activity. This method for manufacturing an ammonia synthesis catalyst includes: a first step for preparing 12CaO·7Al 2 O 3 having a specific surface area of 5 m 2 /g or above; a second step for supporting a ruthenium compound on the 12CaO·7Al 2 O 3 ; and a third step for performing a reduction process on the 12CaO·7Al 2 O 3 supporting the ruthenium compound, obtained in the second step. This invention is characterized in that the reduction process is performed until the average particle diameter of the ruthenium after the reduction process has increased by at least 15% in relation to the average particle diameter of the ruthenium before the reduction process.
专利号:US-10202546-B2 优先权日:2010-03-23 标 题:Ligands for semiconductor nanocrystals 发明人:HAN HEE-SUN; LIU WENHAO; BAWENDI MOUNGI G 权利人:MASSACHUSETTS INST TECHNOLOGY 摘要:In this invention, polyimidazole ligands (PILs) incorporating pendant imidazole moieties for nanocrystal binding and either sulfonatebetaine, carboxybetaine, or phosphocholinebetaine moieties for water-solubilization have been developed. Greatly enhanced stability of nanocrystals (both over time and in wide pH range) was achieved by incorporating multi-dentate imidazole moieties which provide strong coordination of the ligand to the nanocrystal surface and prevent aggregation of nanocrystals. Synthesis of betaine PILs was developed by modifying the synthesis of recently developed PEG containing poly imidazole ligands (PEG PILs). These nanocrystals are compact, water soluble, and biocompatible.
