摘要
This work demonstrates that in situ formation of carbonate layer on the surface of Ba_(0.5)Sr_(0.5)Co_(0.8)Fe_(0.2)O_(3-δ)(BSCF)obtained by exposure to CO_2 during heating between 500℃ and 700℃ can provide enhanced oxygen evolution reaction(OER)performance and durability in an alkaline solution relative to the original BSCF.Three temperatures,i.e., 500℃,600℃,and 700℃ were chosen to perform the CO_2 thermal treatment,resulting into BSCF-500,BSCF-600,and BSCF-700 samples.The OER was enhanced in the order of BSCF-500        This work demonstrates that in situ formation of carbonate layer on the surface of Ba_(0.5)Sr_(0.5)Co_(0.8)Fe_(0.2)O_(3-δ)(BSCF)obtained by exposure to CO_2 during heating between 500℃ and 700℃ can provide enhanced oxygen evolution reaction(OER)performance and durability in an alkaline solution relative to the original BSCF.Three temperatures,i.e., 500℃,600℃,and 700℃ were chosen to perform the CO_2 thermal treatment,resulting into BSCF-500,BSCF-600,and BSCF-700 samples.The OER was enhanced in the order of BSCF-500
