This study aims to investigate the effect of an engineered microstructure on the oxygen permeation property of a BaBi0.2Co0.35Fe0.45O3-delta (BBCF) type perovskite membrane. The interconnected multi-level cross-linked structure of the BBCF membrane has been synthesized by mimicking a common laboratory grade filter paper. The controlled calcination of the cellulose matrix results in a single phase BBCF structure when calcined at 950 degrees C in air. The average diameter of the interconnected BBCF fiber is about 1 mu m as confirmed by FESEM. The electrical conductivity is measured to be similar to 20 S cm(-1) at 800 degrees C, higher than that of other conventionally prepared BBCF based membranes. The perovskite membrane derived by exo-templating of the filter paper's cellulose fiber reveals an enhanced oxygen permeation flux of 0.98 ml min (1) cm (2) at 900 degrees C.
