Title:
METHOD FOR PRODUCING CORE-SHELL MAGNETIC ALLOY NANOPARTICLE
Document Type and Number:
WIPO Patent Application WO/2011/156952
Kind Code:
A1
Abstract:
A method for producing core-shell magnetic alloy nanoparticles comprises the following steps: step 1, dissolving nickel compound in a solvent to produce a solution; step 2, adding a surfactant into the solution obtained from step 1; step 3, dissolving first reducing agent in a solvent to produce first reducing solution; step 4, adding the first reducing solution of step 3 into the solution obtained from step 2 while stirring, and obtaining nickel nano-collosol by stirring and aging; step 5, adding a metallic compound into the nickel nano-collosol of step 4; step 6, dissolving second reducing agent in a solvent to produce second reducing solution; step 7, adding the second reducing solution obtained from step 6 into the mixed solution obtained from step 5; step 8, removing the upper liquid from the product obtained from step 7 after static settling, then re-dispersing in water or absolute ethyl alcohol to obtain the core-shell magnetic alloy nanoparticles using nickel as the core.
