Boosting the oxygen evolution catalytic performance of perovskites via optimizing calcination temperature
We report a facile and universal strategy with simultaneous modulation of intrinsic activity and active site numbers to optimize the catalytic performance of perovskites via controlling calcination temperature. As a proof-of-concept, the optimized SCF-800 perovskite (SrCo 0.5 Fe 0.5 O 3−δ prepared w...

prepared with a calcination temperature of 800 °C) shows prominent OER activity (

on a glassy carbon electrode in 0.1 M KOH), outperforming the benchmark noble-metal RuO

and ranking the highest among perovskite-based catalysts reported to date. Experimental results reveal that the reduced particle size (increased surface area) due to a lower calcination temperature provides more active sites, and that the favorable electronic structure with high covalency of metal–oxygen bonds, as demonstrated by advanced soft X-ray absorption spectroscopy (sXAS), contributes to the intrinsic activity enhancement. This work provides a new and facile way for improving the catalytic performance
