In all the literature researchers report the that they have done it in continuous flow of N2 gas. My doubt is in what may happen if we do that in ambient atmosphere?
They add organic precursor of metal in boiling non polar organic solvent (these people do it in N2 atmosphere at 250-300 C).
The answer depends on the precursor used and the target composition of the product. Under inert, there is a chance to get metal nanoparticles (however, this is not a must). In air, you will most likely get metal oxide.
In ambient atmosphere you are most likely to get oxidized nano-particles(NP).. whereas in N2 atmosphere, depending on the 'organic precursor', temperature and time.. you may get unoxidized & carbon coated NPs
Ok, if you aim to prepare metal oxide (especially highest oxide of a transition metal), you should likely go for air atmosphere.
When you use novel metal precursors you get metals after decomposition in air.
i want to prepare some transition metal oxide based ferrite nanoparticles. May i do it in open atmosphere.
