Recently, Master candidate Dandan He has published a new paper "Enhanced durability and activity of the perovskite electrocatalyst Pr0.5Ba0.5CoO3- by Ca doping for the oxygen evolution reaction at room temperature" in Chem. Commun. (DOI: 10.1039/C7CC00786H) reporting a promising Ca doping approach 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.Link
