Oriented CoSAPO‐5 Membranes by Microwave‐Enhanced Growth on TiO₂‐Coated Porous Alumina

Microwaving plates: A facile method was developed for the fabrication of preferentially c-oriented cobalt-substituted silicoaluminophosphate-5 (CoSAPO-5) membranes on porous alumina supports. In situ microwave growth using a slip-coated TiO2 layer on the support surface resulted in an oriented CoSAPO-5 crystal layer, which was evolved into a defect-free membrane by improving crystalline intergrowth through secondary hydrothermal microwave growth.
