Enhanced durability and activity of the perovskite electrocatalyst Pr0.5Ba0.5CoO3−δ by Ca doping for the oxygen evolution reaction at room temperature
A promising Ca doping approach was reported to improve the durability and electrocatalytic OER activity of the perovskite Pr0.5Ba0.5CoO3−δ (PBC). Compared to the pristine PBC, the electrocatalytic activity of Ca-doped Pr0.5Ba0.3Ca0.2CoO3−δ perovskite was increased by ca. 90%. More importantly, its durability was significantly enhanced after doping with calcium.
