Preparation of non-permselective sulfated zirconia catalytic membrane for use in a catalytic membrane reactor

- Cost-effective sulfated zirconia catalytic membrane was prepared.
- Aluminum isopropylate and silica powder were used to facilitate layers preparation.
- Coating sol with strong acid media was not usable for fabrication of layers.
- The tetragonal to monoclinic phase transformation was appropriately prevented.
- The membrane had desirable crystalline phase, porous and crack-free microstructure.
