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.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
