Structure and Properties of La_2NiO_(4+δ) Oxygen Permeation Membranes
Source abstract
Abstract
The structure and the permeability of La2NiO4+δ oxygen permeating membranes were discussed. TEM studies of La2NiO4+δ show that La2NiO4+δ contains a large amount of interstitial oxygen and exhibits a superstructure behavior owing to long range ordering of interstitial oxygen. The oxygen permeation flux through La2NiO4+δ was determined and the relationship between mechanism of oxygen permeability and structure was discussed. The results indicate that the oxygen transportation by interstitial mechanism is easier than that by vacancy mechanism.
