I have been working on synthesis of tungsten nanoparticles via thermal plasma route, but unfortunately I am not getting good particle morphology (spherical, cylindrical etc). How to control particle morphology in such a plasma system.
Generally, hydrothermal procedures tends to get good shape and morphology of nanoparticles. Also, by using autoclave nice shape and morphology can come. But it mainly depends upon the template you are using, and the reaction rates.
