The study successfully synthesized YBaCo4O7+delta sample using a glycine-complex decomposition method at a low temperature, and demonstrated its superior oxygen storage performance in temperature swing adsorption process.
The present study explores the oxygen storage capacity of YBaCo4O7+delta prepared by a glycine-complex decomposition method. We reported for the first time that the YBaCo4O7+delta sample was successfully synthesized at such a low temperature of 800 degrees C by this method. The YBCO-800 N sample exhibited a faster oxygen absorption/desorption speed than that of high calcination temperature samples, and the time required for complete oxygen storage/release was 5 and 6 min at 360 degrees C, respectively. Moreover, the superior performance observed for this product in the temperature swing adsorption process makes it a promising candidate in oxygen production technologies. This research demonstrated that the glycine-complex decomposition method is an effective method for improving the oxygen storage property of YBaCo4O7+delta and provides a new insight into designing other novel oxygen storage materials.
