Disclosed is a method of decontamination by exposing a zirconium oxy(hydroxide) aerogel to a liquid, vapor, or gaseous sample suspected of containing a phosphonate compound. The aerogel may be doped with Fe.sup.3+ ions, Ce.sup.3+ ions, or SO.sub.4.sup.2− ions. The aerogel may be made by: providing a solution of ZrCl.sub.4; FeCl.sub.3, CeCl.sub.3, or Zr(SO.sub.4).sub.2; and a solvent; adding a cyclic ether to the solution to form a gel; infiltrating the gel with liquid carbon dioxide; applying a temperature and pressure to form supercritical fluid carbon dioxide; and removing the carbon dioxide for form an aerogel.

The present invention generally relates to a method for preparing metal oxide nanosheets. In a preferred embodiment, graphene oxide (GO) or graphite oxide is employed as a template or structure directing agent for the formation of the metal oxide nanosheets, wherein the template is mixed with metal oxide precursor to form a metal oxide precursor-bonded template. Subsequently, the metal oxide precursor-bonded template is calcined to form the metal oxide nanosheets. The present invention also relates to a lithium-ion battery anode comprising the metal oxide nanosheets. In a further preferred embodiment, the battery anode may comprise a reduced template, which is reduced graphene oxide (rGO) or reduced graphite oxide.
