Abstract
In embodiments a metal or metal alloy nanowires are assembled into a nanoporous membrane that can be used in methods for catalyzing various reactions under low pressures and achieving high flow rate of the reactions. In embodiments, the membranes of the disclosure can catalyze CuAAC reactions with high efficiency and minimum leaching of active Cu species.
Claims14
A membrane for a catalyzing flow reactor, comprising:
- metal-containing or metal-alloy containing nanowires self-assembled into a porous nanostructure, wherein the porous nanostructure has a thickness of about 10 nm to about 1 cm, and the nanowires have a diameter of about 1 nm to about 500 nm, and an aspect ratio of about 10 to about 100,000, wherein the metal-containing or metal-alloy containing nanowires each comprises an exterior surface arranged so that the metal or metal alloy of the metal-containing or metal-alloy containing nanowires is exposed to one or more reactants during flow of the reactants through the membrane to catalyze a reaction of the one or more reactants through contact with the exposed metal or metal-alloy during flow-through of the reactants through the membrane.
A membrane for a catalyzing flow reactor, comprising:
- nanowires self-assembled into a porous nanostructure, wherein the nanowires comprise copper, the porous nanostructure has a thickness of about 10 nm to about 1 cm, and the nanowires have a diameter of about 1 nm to about 500 nm, and an aspect ratio of about 10 to about 100,000, wherein the nanowires each comprises one or more copper species arranged on an exterior surface such that the one or more copper species are exposed to one or more reactants during flow of the reactants through the membrane to catalyze a reaction of the one or more reactants through contact with the exposed metal or metal-alloy during flow-through of the reactants through the membrane.
