Abstract
A porous sintered clay mineral matrix that contains aluminum and is doped with 0.1-20 mol %, based on the amount of the aluminum, one or more transition metals, one or more post-transition metals, one or more rare earth metals, or a combination thereof. An example is a kaolinite matrix. The matrix can be made from a calcined clay mineral powder that contains aluminum and is doped with at least one of these metals. Also disclosed are methods of preparing the above-described matrix and powder.
