1. A composition comprising:
a mixed metal oxide that is at least partially crystalline and comprises tungsten, zirconium, and a variable oxidation state metal;
wherein the variable oxidation state metal comprises a metal selected from the group consisting of Fe, Mn, Co, Cu, Ce, Ni, and any combination thereof;
wherein the mixed metal oxide comprises about 5 wt. % to about 25 wt. % tungsten, about 40 wt. % to about 70 wt. % zirconium, and about 0.01 wt. % to about 2 wt. % variable oxidation state metal, each based on a total mass of the mixed metal oxide; and
wherein the mixed metal oxide has a total surface area of between 50 m2/g and 150 m2/g as measured according to ISO 9277, and at least one of the following:
an ammonia uptake of about 0.05 to about 0.3 mmol/g as measured by temperature programmed adsorption/desorption, or
a collidine uptake of about 100 μmol/g or greater as measured gravimetrically.
