Design and synthesis of MOF-derived CuO/g-C3N4 composites with octahedral structures as advanced anode materials for asymmetric supercapacitors with high energy and power densities

Two-component composites consisting of transition metal copper oxide (CuO) and graphite carbon nitride (g-C 3 N 4 ) were successfully synthesized. This CuO/g-C 3 N 4 displays a high reversible specific capacity (1530.4 F g −1 , 2 A g −1 ) as an anode material.
