Abstract

A promising Ca doping approach was reported to improve the durability and electrocatalytic OER activity of the perovskite Pr_0.5Ba_0.5CoO_3−δ (PBC). Compared to the pristine PBC, the electrocatalytic activity of Ca-doped Pr_0.5Ba_0.3Ca_0.2CoO_3−δ perovskite was increased by ca. 90%. More importantly, its durability was significantly enhanced after doping with calcium.
