Claim:
1. A method for synthesis of a porous solid oxide matrix comprising: synthesizing a composite by co-precipitating a ceramic material with a sacrificial material, the method of co-precipitating comprising combining stoichiometric amounts of starting materials including Ce(NO sintering the composite; reducing the sacrificial material of the sintered composite; removing the reduced sacrificial material from the sintered composite to form the porous solid oxide matrix; and controlling a median pore size of the porous solid oxide matrix by controlling a sintering temperature of the composite and a volume fraction of the sacrificial material; wherein an increase in the sintering temperature at a given volume fraction of the sacrificial material will increase the median pore size of the porous solid oxide matrix without an equivalent increase in porosity of the porous solid oxide matrix.
