	Claims
1. A method of producing a nanoparticulate catalyst comprising multivalent iron from an aqueous solution, comprising the steps of: (a) oxidizing or allowing to oxidize the aqueous solution comprising multivalent iron; (b) collecting precipitated nanoparticles or aggregated nanoparticles.
2. The method of claim 1 wherein the aqueous solution comprises groundwater.
3. The method of claim 2 comprising the further step of amending the aqueous solution with one or more additional transition metals, prior to the oxidation step.
4. The method of claim 3 wherein the aqueous solution is amended with copper ions.
5. A nanoparticulate catalyst comprising multivalent iron, at least one iron oxide and at least one iron hydroxide.
6. The catalyst of claim 5 further comprising calcium carbonate.
7. A method of using a nanoparticulate catalyst of claim 5 to produce crystaline cellulose from biomass comprising the steps of: (a) reacting the biomass in an aqueous slurry having a pH less than 7, comprising the catalyst and hydrogen peroxide.
What is claimed is:
1. A method of producing a nanoparticulate catalyst comprising multivalent iron from an aqueous solution, comprising the steps of: (a) oxidizing or allowing to oxidize the aqueous solution comprising multivalent iron; (b) collecting precipitated nanoparticles or aggregated nanoparticles.
2. The method of claim 1 wherein the aqueous solution comprises groundwater.
3. The method of claim 2 comprising the further step of amending the aqueous solution with one or more additional transition metals, prior to the oxidation step.
4. The method of claim 3 wherein the aqueous solution is amended with copper ions.
5. A nanoparticulate catalyst comprising multivalent iron, at least one iron oxide and at least one iron hydroxide.
6. The catalyst of claim 5 further comprising calcium carbonate,
7. A method of using a nanoparticulate catalyst of claim 5 to produce crystaline cellulose from biomass comprising the steps of: (a) reacting the biomass in an aqueous slurry having a pH less than 7, comprising the catalyst and hydrogen peroxide.
