Abstract
Ceramic proton-conducting oxide membranes are described herein, which are useful for separating steam from organic chemicals under process conditions. The membranes have a layered structure, with a dense film of the perovskite over a porous composite substrate comprising the perovskite material and a metallic material (e.g., Ni, Cu, or Pt). The perovskite comprises an ABO-type structure, where 'A' is Ba and 'B' is a specified combination of Ce, Zr, and Y. The perovskite ceramic materials described herein have an empirical formula of Ba(CeZrY)O, wherein 0<x<0.8 (e.g., 0.1≤x≤0.7 or 0.2≤x≤0.5); and 0.05≤n≤0.2; and δ=n/2. In some embodiments n is about 0.2. In some other embodiments 0.6≤x≤0.8; and n is about 0.2, such as Ba(CeZrY)O, also referred to herein as BCZY712.
