“…The Specific surface area calculated from the Brunauer-Emmett-Teller (BET) isotherms is 46 m 2 g −1 for a g-C 3 N 4 @ZnCo 2 O 4 sample which significantly greater than the surface area for pristine ZnCo 2 O 4 (22 m 2 g −1 ). This increase in surface area of g-C 3 N 4 @ZnCo 2 O 4 composite could be ascribed to the incorporation of Carbon nitride, which leads to the formation of more numbers of pores 15 . The BJH plot for both the samples displays the pore size within the range of 2 to 50 nm, which shows the mesoporous nature of the samples.…”

this study reports a unique graphitic-c 3 n 4 supported Znco 2 o 4 composite, synthesized through a facile hydrothermal method to enhance the electrochemical performance of the electrode. the g-c 3 n 4 @ Znco 2 o 4 hybrid composite based electrode exhibits a significant increase in specific surface area and maximum specific capacity of 157 mAhg −1 at 4 Ag −1. Moreover, g-c 3 n 4 @Znco 2 o 4 electrode maintained significant capacity retention of 90% up to 2500 cycles. Utilizing this composite in the development of the symmetric device, g-c 3 n 4 @Znco 2 o 4 //g-c 3 n 4 @Znco 2 o 4 displays a specific capacity of 121 mAhg −1. The device exhibits an energy density of 39 Whkg −1 with an equivalent power density of 1478 Wkg −1. A good cycling stability performance with an energy efficiency of 75% and capacity retention of 71% was observed up to 10,000 cycles. The superior performance of g-C 3 n 4 @Znco 2 o 4 is attributed to the support of the g-c 3 n 4 which increases the surface area, electroactive sites and provides chemical stability for electrochemical performance. the outstanding performance of this exclusive device symbolizes remarkable progress in the direction of high-performance energy storage applications.

Pseudocapacitive materials are used for supercapacitor applications due to their exceptionally high capacitance and low cost. Good capacitive performance of the pseudocapacitive materials at high active mass loadings is vital for the development of the next generation of supercapacitor devices. This review describes recent advances in materials and nanotechnologies, which allows the development of advanced pseudocapacitive devices with high active mass. An important breakthrough is the discovery of novel dispersing and capping agents for the colloidal processing of nanoparticles. Particularly important are novel co‐dispersants that exhibit enhanced adsorption on materials of different types, such as inorganic nanoparticles, carbon nanotubes, and graphene. Conceptually new strategies are designed to fabricate coated particles. Recent innovations pave the way for the development of multifunctional redox‐active dopants‐dispersants and dopants‐oxidants to manufacture conductive polymer composites. Among the most important advances in nanotechnology is the development of template methods and heterocoagulation techniques for composite manufacturing. The progress in the design of novel surface modification techniques and materials, discovery of advanced anchoring groups, and development of liquid–liquid extraction allows agglomerate‐free processing of nanomaterials and composites. This review describes fundamental aspects of novel technologies and their applications in the manufacturing of pseudocapacitive devices for energy storage.
