Abstract:Enhancing catalytic efficiency, achieving controlled synthesis, and lowering production costs are crucial for promoting the use of cobalt oxide (CoO x )/cobalt nitride (CoN x ) composites in full water splitting and electrochemical sensing. In this study, a three-dimensional (3D) hierarchically porous material composed of numerous two-dimensional (2D) porous CoO x /CoN x nanosheets (denoted as CoO x /CoN x NSs) was synthesized by using cobalt oxalates (COs) recycled from spent lithium-ion batteries. In a 1.0 M… Show more
