The invention claimed is: 1. A method for preparing a catalyst comprising: applying colloidal zinc oxide to a solid core material to form a shell of zinc oxide around the solid core material, and applying one or more metals selected from a group consisting of cobalt, iron, ruthenium, and nickel to
The invention claimed is: 1. A method for preparing a catalyst comprising: applying colloidal zinc oxide to a solid core material to form a shell of zinc oxide around the solid core material, and applying one or more metals selected from a group consisting of cobalt, iron, ruthenium, and nickel to the shell of zinc oxide. 2. The method according to claim 1 further comprising applying at least one charged ionic species to the solid core material prior to applying the colloidal zinc oxide to the solid core material. 3. The method according to claim 2 further comprising applying at least one oxidic material other than zinc oxide to the solid core material prior to applying the colloidal zinc oxide to the solid core material. 4. The method according to claim 3 further comprising applying at least one ionic species to the solid core material prior to applying the colloidal zinc oxide to the solid core material. 5. The method according to claim 3, wherein the oxidic material comprises silica, tungsten oxide, alumina-silica, or combinations thereof. 6. The method according to claim 2, wherein applying at least one charged ionic species to the solid core material comprises applying a cationic material to the solid core material and applying an anionic material to the solid core material, or vice versa. 7. The method according to claim 6, wherein the cationic material comprises poly diallyldimethyl ammoniumchloride. 8. The method according to claim 6, wherein the anionic material comprises a polystyrene sulfonate salt. 9. The method according to claim 2, wherein the charged ionic species comprise charged polymeric ionic species. 10. The method according to claim 1, wherein the colloidal zinc oxide has a particle size of less than 150 nm. 11. The method according to claim 1 further comprising converting the solid core material to an active material. 12. A method for preparing a catalyst comprising: applying a colloidal zinc oxide solution to a solid core material to form a shell of zinc oxide around the solid core material, and applying cobalt to the shell of zinc oxide. 13. The method according to claim 12 further comprising applying at least one charged ionic species to the solid core material prior to applying the colloidal zinc oxide solution to the solid core material. 14. The method according to claim 13 further comprising applying at least one oxidic material other than zinc oxide to the solid core material prior to applying the colloidal zinc oxide solution to the solid core material. 15. The method according to claim 14 further comprising applying at least one ionic species to the solid core material prior to applying the colloidal zinc oxide solution to the solid core material. 16. The method according to claim 13, wherein applying at least one charged ionic species to the solid core material comprises applying a cationic material to the solid core material and applying an anionic material to the solid core material, or vice versa. 17. A method for preparing a catalyst comprising: applying at least one charged ionic species to a solid core material, optionally applying at least one oxidic material other than zinc oxide to the solid core material, applying colloidal zinc oxide to the solid core material, and applying one or more metals selected from a group consisting of cobalt, iron, ruthenium, and nickel to the solid core material. 18. The method according to claim 17 further comprising applying at least one charged ionic species to the solid core material after applying at least one oxidic material other than zinc oxide to the solid core material and prior to applying the colloidal zinc oxide to the solid core material. 19. The method according to claim 17, wherein applying at least one charged ionic species to the solid core material comprises applying a cationic material to the solid core material and applying an anionic material to the solid core material, or vice versa.
