Title:
NICKEL NANO MATERIAL HAVING POROUS TUBULAR HOLLOW STRUCTURE, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/072631
Kind Code:
A1
Abstract:
A nickel nano material having a porous tubular hollow structure, and a manufacturing method therefor. The nickel nano material has a porous tubular structure, which has multiple holes on the surface and a hollow cavity inside, and two-dimensional or three-dimensional holes are formed on the wall. First, a silver nanowire is prepared by means of a polyol process to serve as a template; then a nickel-silver composite core-shell nano structure is obtained after a reaction; after washing by ultrapure water, the nickel-silver composite core-shell nano structure is dispersed in water and subjected to annealing under a certain temperature to obtain nickel-silver alloy; the alloy is placed in concentrated nitric acid to undergo corrosion for a period of time; finally, separation is performed to obtain a nickel nano material having a tubular hollow structure similar to a macro porous nickel shape. The method has a simple and easy-to-operate process, good repeatability, and low costs. The obtained nickel nano material can be applied to fields such as chemical and electrochemical catalysis, chemical sensors, biomolecular sensors, optical information storage, drug targeting carriers, and photothermal therapy for cancer cells.
