摘要
The creation of innovative carbon materials with enhanced porous architectures, high surface areas, high conductivities, and high electrochemical stability is necessary for the advancement of supercapacitors and sensors in the future. In the past, different methods have been used to make nano porous carbons (NPCs), such as physical and chemical activation, carbonization of polymer precursors, templated synthesis, etc. Mesoporous materials, an inorganic solid, have several possible applications. Over the years, researchers have explored MOFs with huge pore volumes and high surface areas, and more recently, great efforts have been made to use MOFs for electrochemical supercapacitor and sensor applications. For use in supercapacitors, the cobalt sulfide (CoS) and CoS@Co-MOF carbon composite materials were made using a hydrothermal procedure assisted by ultrasonication. The synthesized composite materials were characterized by structural, morphological, and electrochemical properties for supercapacitor applications. The composite electrode that was created for use in supercapacitors has good electrochemical characteristics. Using 1 M KOH electrolyte, the resultant specific capacitance was ~1020 F/g at the current density of 10 mA/cm2 with excellent cycle stability. In addition, the synthesized CoS@Co-MOF composite exhibits significant glucose detection, reproducibility, and stability via the electrodeposition process.
