Graphitic carbon nitride (g-C3N4) 3 N 4 ) decorated on CuCo2O4 2 O 4 nanosphere composites for enhanced electrochemical performance for energy storage applications

Researchers sought to develop high-performance electrode materials to meet the rising need for renewable energy storage systems in order to build smart technology gadgets with portable characteristics and with global energy security. ACuCo2O4/g-C3N4 2 O 4 /g-C 3 N 4 nanocomposite was synthesised by employing a facile hydrothermal method. The XRD, FTIR, TEM, XPS, and FESEM results conformed the formation of CuCo2O4/g-C3N4 2 O 4 /g-C 3 N 4 to a spinel cubic structure in space group Fd3m.For a CuCo2O4/g-C3N4 2 O 4 /g-C 3 N 4 sample, the specific surface area determined using the Brunauer-Emmett-Teller (BET) isotherms is 51 m 2 g- 1 , which is much higher than the surface area for pure CuCo2O4 2 O 4 (32 m2g-1). 2 g- 1 ). The g-C3N4 3 N 4 (n-type) wrapped CuCo2O4 2 O 4 (p-type) nanoparticles exhibits incredible specific capacitance of 1948 Fg- 1 at 1 Ag- 1 and Power density of 1556 W/ kg at 6 Ag-- 1 ). Moreover, the long life cycle stability shows 88% capacitance returns after 8000 charge discharge cycles.
