Abstract
Compositions of mixed metal oxides and mixed metal oxide catalysts are provided. The mixed metal oxide compositions and mixed metal oxide catalysts comprise aluminum, cobalt and copper, wherein at least a portion of the composition comprises a ternary spinel structure. Processes for the preparation of mixed metal oxide catalysts, and methods of reducing pollutants with a mixed metal oxide composition or mixed metal oxide catalyst described herein are also provided.
Claims21
A mixed metal oxide catalyst comprising aluminum, cobalt and copper, wherein the elemental ratio of aluminum to cobalt to copper is X:Y:1, wherein X is in the range of about 7 to about 20, and Y is in the range of about 3 to about 15, wherein at least a portion of the catalyst comprises a ternary spinel structure.
A process for preparing a mixed metal oxide catalyst comprising:
- (a) preparing a dispersion comprising a metal solution, wherein the metal solution comprises a solvent, and aluminium, copper and cobalt in solution, wherein the total concentration of metal ions in the solution is between about 0.5 M and about 5 M;
- (b) applying the dispersion to a substrate;
- (c) removing the solvent from the substrate to form a catalyst precursor;
- and
- (d) calcining the catalyst precursor to produce the mixed metal oxide catalyst, wherein the mixed metal oxide catalyst comprises an elemental ratio of aluminum to cobalt to copper is X:Y:1, wherein X is in the range of about 7 to about 20, and Y is in the range of about 3 to about 15.
