Grand Challenges of Perovskite and Metal Oxide-based Membrane: A Form of Dual-layer Hollow Fibre

Perovskite and metal oxides-based dual-layer hollow fibre membrane (DHF) has a high appeal as separator catalyst for methane conversion application which operated at intermediate temperature. The mostly fabricated via the co-extrusion followed by co-sintering method, is quite challenging, due to complexity handle barrier between layers from delamination, cracking crystal structure distortion affects material performance in DHF form. This recent review clarifies challenges fabrication process regulate physical chemical properties terms of mechanical strength, tightness, elemental distribution, stability. based focuses on NiO-YSZ inner layer directly interconnected with LSCF-YSZ outer layer. understanding fabrication, will further reduce crucial errors accelerate improvement such syngas, methanol long-chain hydrocarbons production, solid oxide fuel cell.
