Chemical production of metal nickel nano-line

Abstract

A process for chemically preparing Ni nanowires includes such steps as using ethanediol as solvent to prepare solution, reacting to generate Ni(OH)2, precursor, and reduction reaction of Ni ions, where the soft template is formed by ethanediol, nickel sulfate is used as main salt and hydrazine hydrate is used as reducer, to form Ni nanowires by autoassembling.

Description

technical field The invention relates to the preparation of one-dimensional powder material by chemical method, in particular to the preparation of metal nickel powder. Background technique Due to the small grain size, large specific surface area, obvious quantum effect and adjustable surface microstructure at the nanoscale, nanomaterials have excellent physical and chemical properties that are different from traditional materials. It has broad application prospects in the fields of catalytic materials and electrode materials. In recent years, nanotechnology has developed from the simple synthesis and characterization of nanomaterials to the design of nanodevices. One-dimensional nanomaterials (such as nanowires) have attracted much attention in the design and application of nanodevices due to their unique quantum transport effects. Metal nanowires with a uniform aspect ratio and a certain length will have important applications in nano-optoelectronic devices and biospect...
