Recent Progress on Mixed Conducting Oxygen Transport Membrane Reactors for Water Splitting Reaction

Catalytic membrane reactors based on mixed conducting oxygen transport membranes (OTMs) have the ability to integrate reaction and separation, and thus simplify the chemical process by coupling oxygen supplying reaction, oxygen separation and oxygen consumption reaction into a single unit.In recent years, more and more attentions have been paid to the mixed conducting OTM reactors for water splitting reaction owing to their applications for preparation and separation of hydrogen.In this article, we summarize the recent progress on mixed conducting OTM reactors for water splitting reaction, including the effects of membrane materials, catalysts and operation conditions on the water splitting involved membrane reactors.Meanwhile, the current existing problems in the above aspects are analyzed, and the future development of membrane materials, membrane structures and catalysts in this field is prospected.We wish this paper will be helpful for the development of the water splitting in membrane reactors.
