Dense Metallic Membranes

Dense metallic membranes are typified by palladium (Pd) membrane for hydrogen permeation and silver (Ag) membrane for oxygen permeation. Pd‐based membranes possess very reasonable hydrogen permeability, but the oxygen permeability of Ag‐based membranes is orders of magnitude lower than the hydrogen permeability of Pd‐based membranes. In recent years, there has been growing interest in the application of MRs for various reactions toward higher conversion and yield improvement.
