“…6. Heteroatom dopants on the carbon surface serve as an effective bridging element for hetero-nanostructures growth and help achieve higher electrolyte ion adsorption than in the pure carbon, [82][83][84][85][86] as an enhancer to improve supercapacitor performance of active electrode [87] or current collector. [88] Eventually, heteroatom doped carbon structures can be used as a current-collector free electrode whereas a metal current collector is essential for metal oxide or conducting polymers electrode, which increases the total mass of electrode.…”

Electrochemical capacitors (best known as supercapacitors) are high‐performance energy storage devices featuring higher capacity than conventional capacitors and higher power densities than batteries, and are among the key enabling technologies of the clean energy future. This review focuses on performance enhancement of carbon‐based supercapacitors by doping other elements (heteroatoms) into the nanostructured carbon electrodes. The nanocarbon materials currently exist in all dimensionalities (from 0D quantum dots to 3D bulk materials) and show good stability and other properties in diverse electrode architectures. However, relatively low energy density and high manufacturing cost impede widespread commercial applications of nanocarbon‐based supercapacitors. Heteroatom doping into the carbon matrix is one of the most promising and versatile ways to enhance the device performance, yet the mechanisms of the doping effects still remain poorly understood. Here the effects of heteroatom doping by boron, nitrogen, sulfur, phosphorus, fluorine, chlorine, silicon, and functionalizing with oxygen on the elemental composition, structure, property, and performance relationships of nanocarbon electrodes are critically examined. The limitations of doping approaches are further discussed and guidelines for reporting the performance of heteroatom doped nanocarbon electrode‐based electrochemical capacitors are proposed. The current challenges and promising future directions for clean energy applications are discussed as well.

“…They are (i) EDLCs, (ii) pseudocapacitors, and (iii) hybrid supercapacitors . In EDLCs, non-faradaic ion adsorption–desorption from the electrode to electrolyte occurred reversibly and involved various carbon-based materials like activated carbon, carbon aerogel, porous carbon, carbon nanofiber, graphene, CNTs, and transition metal carbides such as MXene. − In pseudocapacitors, complete reversible faradaic reaction of the active metal of the electrode occurred over its surface in aqueous electrolytic solution and included a variety of sulfides, oxides, and hydroxides, preferably from the d-block element. − Conducting polymers such as PANI, PEDOT, as well as MOF were also incorporated under this category. − The third type called as hybrid supercapacitors is available, which includes the composites of carbon materials such as RGO and CNT with various metal sulfides, oxides, and hydroxides as well as with conducting polymers. − From the variety of electrode materials, graphene has been well recognized for the energy storage applications because of its multifarious fascinating properties . However, the restacking between the graphene sheets is the major shortcoming that deteriorates the electrochemical charge storage behavior.…”

Bifunctional properties of nanomaterials are currently more focused as well as advantageous in various domains of electrochemistry. The supercapacitor analyses show that the N,S dual-doped graphene derived from ammonium persulfate (APS) and graphene oxide (GO) in a weight ratio of 1:1 delivered an increased gravimetric capacitance of 393 F g −1 in 1 M H 2 SO 4 solution at 0.5 A g −1 . The full-cell investigations revealed that the symmetric APSGO-1 cell in 0.01 M KI/1 M H 2 SO 4 attained the energy density of 24 W h kg −1 at 2 A g −1 along with 92% retention from its initial capacitance over 10,000 cycles. The glassy carbon electrodes modified with APSGO (APSGO/GCE) were investigated for electrochemical sensing of dihydroxybenzene isomers, specifically hydroquinone (HQ) and resorcinol (RS). The material demonstrated the ability to simultaneously sense both isomers, displaying well-defined peaks and an adequate potential difference between them. Sensing analysis revealed that APSGO1/GCE exhibited superior performance, achieving low detection limits of 0.1 and 0.2 μM in the linear range from 0.3 to 200.0 μM for HQ and RS, respectively, in 0.1 M PBS (pH 7.0). The practical applicability of the APSGO1/GCE sensor was successfully demonstrated in tap water samples, yielding promising results.

[10][11][12][13][14][15][16] Graphene has given comprehensive focus as a propitious EDLC electrode material, on account of its high theoretical specific surface area (2630 m 2 g À 1 ), improved intrinsic carrier mobility (2*10 5 cm 2 V À 1 s À 1 ), extraordinary thermal conductivity (5000 W m À 1 K À 1 ) and electrical conductivity which is extremely high (~106 S cm À 2 ). [17] Still, the restacking or aggregation due to the severe van der Waals attraction within the graphene sheets is inevitable and would prominently weaken the ionic-accessible surface area.…”

Doping of graphene with variety of heteroatoms is presently focused for electrochemical supercapacitor applications because it functions as a hybrid supercapacitor. Herewith, we report the fabrication of Se‐doped graphene with selenium dioxide using a supercritical fluid technique. Both the existence as well as the quantity of Se‐doping in graphene are established using XPS and EDAX techniques. The Se‐doped graphene derived from the weight ratio of selenium dioxide and graphene oxide of 1 : 3 resulted in an enriched gravimetric capacitance achieving 581 F g−1 (1 M H2SO4). The specific capacity of the optimised Se‐doped graphene based symmetric supercapacitor in 0.01 M solution of ammonium metavanadate in 1 M H2SO4 solution is found to be 420 C g−1 and attained an improved capacitance retention of 85% over 50000 cycles along with 94% coulombic efficiency. The energy density of the Se‐doped graphene symmetric supercapacitor is found to be 23.33 Wh kg−1 in 0.01 M solution of ammonium metavanadate in 1 M H2SO4 solution.
