摘要：

A promising Ca doping approach was reported to improve the durability and electrocatalytic OER activity of the perovskite Pr0.5Ba0.5CoO3-delta (PBC). Compared to the pristine PBC, the electrocatalytic activity of Ca-doped Pr0.5Ba0.3Ca0.2CoO3-delta perovskite was increased by ca. 90%. More importantly, its durability was significantly enhanced after doping with calcium.
