Method for preparation of multifarious Sb2O3 nanostructure

Abstract

The invention discloses a preparing method of multi-branched structure of Sb2O3, nanometer array, nanometer rod and nanometer slice, which comprises the following steps: making elemental carbon (graphite powder, activated char and carbon nanometer pipe) and nanometer ATO powder as raw material; setting Ar as carrier gas; adopting CVD method; leading into O2 of 1sccm till reaching design temperature; setting heating-up temperature at 1000-1200 deg.c, reacting time at 1-2.5 h and Ar flow rate at 30-70sccm; proceeding a series of reaction; getting the product.

Description

technical field [0001] The invention relates to a method of using simple carbon as a reducing agent to prepare a variety of Sb by using chemical vapor deposition (CVD) to reduce ATO nanoparticles at high temperature. 2 o 3 nanostructuring method. Background technique [0002] With the rapid development of society, the densification of urban population, the densification and high-rise of residential and office buildings, commercial buildings and other public buildings, the risk factors and frequency of fire in social life and production areas have also increased. In recent years, the losses caused by fires in various countries are on the rise. In order to prevent unburned, western countries, especially developed industrial countries such as the United States, Japan, and Western Europe, have devoted themselves to the development of flame retardant industry. my country's flame retardant industry started late, but has developed to a certain ext...
