A novel cobalt-free perovskite based on Ba_0.5Sr_0.5Fe_0.8Zn_0.2O_3-δ (BSFZ) were prepared by EDTA-citric acid method. The lattice constants of the BSFZ perovskite were characterized by in situ high-temperature X-ray diffraction (HTXRD). The thermal expansion coefficient of BSFZ is 10.5×10^-6 K^-1, which is lower than that of cobalt-based perovskite materials. The BSFZ membrane was also used to construct reactors for the partial oxidation of methane (POM) to syngas. Results show that the BSFZ membrane can be operated for the POM reaction for more than 100 h without any fractures. The CO selectivity of 97% is obtained.The steady oxygen permeation flux reaches around 2.5 mL/min cm² during POM reaction.
