专利号:US-2022411943-A1 优先权日:2021-06-23 标 题 :Process for the Electrochemical Synthesis of Green Urea, an Electrochemical Cell for the Electrochemical Synthesis of Green Urea and the Green Urea Produced Thereby 发明人:GHORAI UTTAM KUMAR; MUKHERJEE Jit; PAUL SOURAV; ADALDER ASHADUL 权利人:GHORAI UTTAM KUMAR; RAMAKRISHNA MISSION VIDYAMANDIRA 摘要:This invention relates to a process for the electrochemical synthesis of green urea, and the urea produced thereby. The electrochemical synthesis of urea involves the reduction of dual purging gases N 2 and CO 2 via six electron transfer process (N 2 +CO 2 +6H + +6e − →CO (NH 2 ) 2 +H 2 O) & reduction of the NO 3 − ions and CO 2 via sixteen electron transfer process (2NO 3 −+CO 2 +18H + +16e − →CO(NH 2 ) 2 +7H 2 O) under ambient condition using copper phthalocyanine (CuPc) catalyst. The binding of two intermediate products during dual reduction simultaneously, leads to the production of urea in water medium under ambient conditions.

In particular, the present disclosure relates to a method of synthesis of copper phthalocyanine using deep eutectic solvent (DES), which can be carried out at low temperature, does not involve use of high boiling solvents, uses less urea and allows solvents used in the process to be recycled.
专利号:US-2023279562-A1 优先权日:2021-12-30 标题 :Process for the Electrochemical Synthesis of Ammonia (NH3) and the Ammonia Produced Thereby 发明人:GHORAI UTTAM KUMAR; PAUL SOURAV; ADALDER ASHADUL; SARKAR SOUGATA 权利人:GHORAI UTTAM KUMAR; RAMAKRISHNA MISSION VIDYAMANDIRA 摘要:This invention relates to a process for the electrochemical synthesis of ammonia (NH3) and the ammonia produced thereby. Ammonia is synthesized by the electrochemical reduction of nitrogenous materials such as nitrogen or nitrates (NO3-) using metal phthalocyanine such as iron phthalocyanine (FePc) or β-cobalt phthalocyanine (CoPc) or iron phthalocyanine-molybdenum disulfide (FePc-MoS2) or cobalt phthalocyanine- carbon nitride (CoPc-C3N4) catalyst at very low pressure and room temperature by applying low potential.

There are disclosed new derivatives of acenes that are fabricated using novel synthesis. For example, the disclosed fabrication strategies have allowed for the first time new aza-tetracene and aza-pentacene derivatives. The HOMO and LUMO energy levels of these materials are tunable through appropriate substitution and as predicted, deepened. There are also disclosed organic photosensitive devices comprising at least one aza-acene such as aza-tetracene and aza-pentacene.
专利号:US-2008305045-A1 优先权日:2007-06-07 标 题 :Methods of synthesis of non-toxic multifunctional nanoparticles and applications 发明人:KUNIYIL PRABHAKARAN; PRABHAKARAN GEETHA 权利人:KUNIYIL PRABHAKARAN; PRABHAKARAN GEETHA 摘要:The present invention involves multifunctional nanoparticle dispersions and methods for making them using sol-gel chemistry, doping, and sonication. These methods avoid the high thermal budget processes of the reference art. The dispersions can accommodate greater concentrations of nanoparticles, dopants, and ions than has previously been possible since these components can be added during synthesis. The unique optical, magnetic, luminescent, metallic, insulating, semi-conducting, and/or conducting properties of these particles can be utilized to enhance photovoltaic cells, portable electronic devices, and biomedical techniques among other applications.
专利号:US-5800796-A 优先权日:1995-10-06 标题 :Composite membrane and use thereof for synthesis of hydrogen peroxide 发明人:WEBB STEVEN P; MCINTYRE JAMES A 权利人:DOW CHEMICAL CO 摘要:This invention is a composite membrane for chemical synthesis, a chemical reactor into which the composite membrane might be incorporated, and a method of using the composite membrane. The composite membrane comprises a substrate, a first side, and a second side, wherein the substrate operatively connects the first side and second side, the first side comprises an oxidizing catalyst and the second side comprises a reducing catalyst. The reducing catalyst comprises, in elemental or combinative form, lanthanum, zinc, cerium, praeseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, bismuth, or indium. A chemical reactor utilizing this composite membrane can react hydrogen and oxygen to form hydrogen peroxide without direct mixture of the reactants.
