Abstract
The present disclosure relates to a method for synthesis of a porous solid oxide matrix. The method includes synthesizing a composite by co-precipitating a porous ceramic material with a sacrificial material. The composite is sintered and the sacrificial material of the sintered composite is reduced. A porous solid oxide matrix is formed from the reduced and sintered composite. Porosity of the solid oxide matrix is controlled by a volume fraction of the sacrificial material or sintering temperature and a volume fraction of the sacrificial material. Pore size of the solid oxide matrix is controlled by sintering temperature and a volume fraction of the sacrificial material.
