Abstract
Nanoplatelet forms of monolayer metal hydroxides are provided, as well as methods for preparing same. The nanoplatelets are suitable for use in antimicrobial compositions, for pressure treating lumber against wood rot, termites, and fungus, for water treatment for the removal of heavy metal contaminants, for the production of plasmonics devices, for the production of ore, or for the recovery of valuable metals in, e.g., fly ash ponds, mine tailings ponds, or other fluids containing the metal in ionic form. The nanoplatelet forms include copper hydroxide nanoplatelets.
Claims19
A nanoplatelet having a metal hydroxide monolayer, produced by:
- mixing a nanoplatelet of magnesium hydroxide into a water column as a precursor to form a core of a monolayer nanoplatelet;
- dissolving metal salts or metal ion sources to supply other metal ions that are dissolved into the water of the water column to supply the other metal ions to self assemble by ion exchange to yield a monolayer shell, thereby creating a metal hydroxide monolayer nanoplatelet.
A nanoplatelet comprising a metal hydroxide monolayer shell, prepared by:
- mixing an insoluble metal hydroxide more active than shell metal ions into a water column containing the shell metal ions as a precursor to forming a core of a monolayer nanoplatelet, wherein the shell metal ions self assemble by ion exchange a monolayer shell on the core, thereby creating a metal hydroxide monolayer nanoplatelet concentrating the shell metal ions in the monolayer shell as an ore to be reduced to a pure element.

A method of pressure treating lumber, comprising:
- exposing the lumber to nanoplatelets having a dimension in the X axis of from about 30 nm to about 3500 nm, a dimension in the Y axis of about 30 nm to about 3500 nm, a dimension in the Z axis of from 1 nm to 400 nm, and an aspect ratio of 15 to 75, wherein the nanoplatelets comprise copper hydroxide, such that the nanoplatelets penetrate into a vasculature of the lumber, whereby a resistance to a destructive organism is imparted to the lumber.
