Cover Picture: One pot production of Co core/carbon shell materials and their electrocatalytic properties (BKCS 1/2024) Yunseok Shin, Sungjin Park

Core‐shell materials containing carbon shells surrounding Co particles are prepared one‐pot process involving thermal treatment of Co(II) acetylacetonate and show excellent electrocatalytic oxygen reduction reaction performance and cyclic durability. The core‐shell materials could have the potential as practical electrocatalysts with high stability. More details are available in the article by Yunseok Shin, Sungjin Park image
