Abstract
Methods for changing the surface area of nanomaterials to improve properties, processing and product manufacturing. These methods are useful for oxides, nitrides, carbides, borides, metals, alloys, chalcogenides, and other compositions.
Claims17
A method for modifying the surface area of a composition of matter comprising:
- preparing nanomaterials composite comprising a sacrificial composition and a desired composition wherein the sacrificial composition retains its identity;
- treating the nanomaterials composite by processing the nanomaterials composite with a solvent;
- wherein the treatment step modifies the surface area of the nanomaterials composite by removing the sacrificial composition;
- and
- collecting treated nanomaterials comprising the desired composition.

A method for modifying the surface area of a composition of matter comprising:
- preparing nanomaterials composite comprising a sacrificial composition and a desired composition wherein the sacrificial composition retains its identity;
- treating the nanomaterials composite by processing the nanomaterials composite under a condition that causes removal of the sacrificial composition and modification of the surface area of the nanomaterials composite;
- and
- collecting the treated nanomaterials composite comprising of the desired composition.
