专利号:WO-2024009318-A1 优先权日:2022-07-02 标题:Boron oxide, borophene and borophane based 2d sheets for hydrogen storage and synthesis thereof 发明人:PALICHA KAUSHIK; Seshadri Harinipriya 权利人:PALICHA KAUSHIK; Seshadri Harinipriya 摘要:The present disclosure provides a method of synthesis of boron oxide, borophene and borophane, where 2D nano sheets of Boron oxide (B2O3) were synthesised utilising liquid exfoliation followed by thermal oxidation of micro boron powder in air at 600-7000C, and then the 2D nano sheets of Boron oxide (B2O3) were reduced by H2 to form borophene and further reduction to borophane, wherein the B2O3 and borophene are used for improved hydrogen storage. The volume percentage of hydrogen stored is 8.645% with borophene formation from B2O3 contributing around 5.124% and borophane from borophene contributing to 3.521%. The capacitance of the hydrogen stored borophene and borophane is obtained as 8.09 F/g. The specific capacity attained via formation of borophene from B2O3 is about 46.1mAh/g and of borophane from borophene is about 39.4 mAh/g.

专利号:US-6869903-B2 优先权日:2002-11-07 标题:Synthesis of polymerization catalyst components 发明人:MATSUNAGA PHILLIP T 权利人:UNIVATION TECH LLC 摘要:The present invention provides a method of synthesizing fluorided metallocene catalyst components comprising contacting at least one fluoriding agent comprising fluorine with one or more alkylated metallocene catalyst components comprising one or more non-halogen leaving groups to produce a fluorided catalyst component; wherein from less than 3 equivalents of fluorine are contacted for every equivalent of leaving group. The method of the invention is exemplified by the following reaction which takes place in a non-coordinating diluent such as pentane: n n nwherein one or both of the “Cpâ€? rings may be substituted with an R group as described herein, and may be bridged. The reaction can be run at any desirable temperature, desirably between 10° C. and 35° C. The reaction product of the BF 3 and dimethyl zirconocene is the fluorided zirconocene. The mole ratio of the BF 3 fluoriding agent and the starting metallocene is less than 2:1 (fluoriding agent:metallocene) in one embodiment, and less than or equal to 1.6:1 in a particular embodiment, and less than or equal to 1.5:1 in a more particular embodiment, and less than or equal to 1.2:1 in yet a more particular mbodiment.
