Thin-film membrane layers coated onto porous supports is an efficient way to obtain high-performance oxygen transport membranes with both good permeability and high mechanical strength. However, conventional preparation methods of membrane supports usually result in highly tortuous channels with high mass transfer resistance. In this work, tubular porous MgO and MgO/CGO supports were fabricated with a simple phase inversion casting method. Finger-like channels are formed during the phase inversion process, which provide a short path for gas transfer through the membrane support. CGO membrane layers were coated onto the support with the dip-coating process. Compatible shrinkage behaviors of the two layers were realized by adjusting the processing conditions. View this paper.
