摘要:The disclosure herein discloses a general method for the synthesis of FeCoNiCu-based high-entropy alloy and their application for electrocatalytic water splitting, belonging to the technical field of preparation of composite materials. The catalytic material for electrolysis of water includes a reaction active material and a support. The reaction active material is FeCoNiCu-based high-entropy alloy nanoparticles such as FeCoNiCuSn, FeCoNiCuMn, FeCoNiCuV or the like. The support is a carbon nanofiber material prepared by electrospinning. The catalytic material for electrolysis of water prepared in the disclosure herein has a high specific surface area, which facilitates diffusion of the electrolyte and desorption of gas. By using the catalytic material for electrolysis of water, hydrogen and oxygen can be produced under alkaline conditions, and the hydrogen production rate under high voltage is much higher than that of a 20% Pt/C electrode. Meanwhile, the carbon nanofibers can effectively protect the high-entropy alloy nanoparticles from erosion of the electrolyte, and endow the catalytic material with good stability.

摘要:Synthesize a nickel oxide-based oxidative dehydrogenation catalyst via a solvent-free process that comprises sequential steps a. mixing without added solvent a combination of a solid nickel precursor, a solid oxalate or oxalic acid and, optionally, a doping amount of a metal precursor for a period of time sufficient to convert the combination to a visually homogenous mixture; and b. calcining the visually homogeneous mixture at a temperature within a range of from greater than 250° C. to less than 800° C. for a time within a range of from 30 minutes to 360 minutes in an oxygen-containing atmosphere, preferably air, to form a calcined oxidative dehydrogenation catalyst. As a modification of the process, add an intermediate step between steps a. and b. to dry the homo geneous mixture at a temperature within a range of from 50° C. to 90° C. for a period of time within a range of from 10 minutes to 600 minutes to form a dried mixture. The resulting catalyst may be used in oxidative dehydrogenation of ethane.

标 题:Low-temperature route for precision synthesis of metal oxide nanoparticles
发明人：ITO DAISUKE; HUTCHISON JAMES E
权利人:UNIV OREGON
摘要:Methods for making metal oxide nanoparticles, including mixed metal oxides and core-shell metal oxide nanoparticles, are disclosed. A solution comprising a metal carboxylate and a carboxylic acid is combined with a solvent comprising an alcohol heated to a temperature ≦250° C. for an effective period of time to form metal oxide nanoparticles. The metal may be a group IIIA metal, a group IVA metal, a transition metal, or a combination thereof. A metal oxide shell may be deposited onto metal oxide nanoparticles by dispersing the metal oxide nanoparticles in an alcohol, adding a metal carboxylate, and maintaining the reaction at a temperature ≦200° C. for an effective period of time to form core-shell nanoparticles. The nanoparticles may have a relative size dispersity of ≦20%, and may further comprise a plurality of carboxylic acid, carboxylate, and/or alcohol ligands coordinated to the nanoparticles' outer surfaces.
