The nanomaterials were synthesized through two methods: topdown and bottomup approaches. In topdown, the bulk materials were transformed into desired nanomaterials by etching and ball milling techniques, but the nanomaterials are obtained in reverse order, followed by colloidal dispersion and solgel method.
