Abstract
A ceramic membrane for oxidative coupling of methane can include a perovskite oxide and catalyst material on a surface of the membrane.
Claims12
A method of making a ceramic membrane comprising:
- dissolving a barium salt, an iron salt, and a zirconium salt in a solvent to form a precursor solution;
- adjusting the pH of the precursor solution to form a mixture;
- drying the mixture to form an ash;
- calcining the ash to form a perovskite oxide;
- and
- distributing a lanthanum oxide catalyst on a surface of the perovskite oxide to form the ceramic membrane;
- wherein the perovskite oxide has the formula BaBO3-δ,
- wherein B is a mixture of Fe and Zr.
