摘要:The invention discloses a method for the synthesis of monodispersed luminescent quantum dots of transition metal dichalcogenides (TMDC), single- or few-layered, using a single-step electrochemical exfoliation that involves dilute ionic liquid and water. The method disclosed helps to obtain nanoclusters of TMDC of desired size including small sizes ranging up to 6 nm, by varying the concentration of the electrolyte and the applied DC voltage. The invention further discloses a method by which mono- or few-layered luminescent transition metal dichalcogenides can be directly deposited onto conducting substrates in a uniform manner. The monodispersed single- or few-layered luminescent TMDC and electro-deposited substrates exhibit improved electronic conductivity and new active sites, making them suitable as high-performance electrocatalysts in hydrogen evolution reactions in solar water-splitting applications and also as electrodes for solar cell applications.

标题:Electrochemical synthesis of ammonia
发明人：DENVIR ADRIAN; MURPHY OLIVER J; CISAR ALAN; ROBERTSON PRISCILLA; USELTON KYLE
摘要:A method for electrochemical synthesis of ammonia gas comprising providing an electrolyte between an anode and a cathode, providing hydrogen gas to the anode, oxidizing negatively charged nitrogen-containing species present in the electrolyte at the anode to form an adsorbed nitrogen species, and reacting the hydrogen with the adsorbed nitrogen species to form ammonia. Preferably, the hydrogen gas is provided to the anode by passing the hydrogen gas through a porous anode substrate. It is also preferred to produce the negatively charged nitrogen-containing species in the electrolyte by reducing nitrogen gas at the cathode. However, the negatively charged nitrogen-containing species may also be provided by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte mixture in a sufficient amount to provide some or all of the nitrogen consumed in the production of ammonia.

摘要:The invention is directed to a simple and new method for the homogeneous synthesis of cellulose ethers. Ionic liquids are not only used as solvent, but also as reaction media for the homogeneous etherification of cellulose. The dissolved cellulose is treated with the etherification agent in the absence of organic and/or inorganic bases and in the absence and/or in the presence of moderate amounts of water. The obtained cellulose ethers show new distributions of substitution on the polymer chain, resulting in new properties and applications.
