“…electron transfer between electrolyte ion/electrode surface [1,3,4]. It is well known that metal oxides/sulfides and conductive polymers are coming under pseudocapacitor and carbon based materials, such as activated carbons, graphene, carbon nanotubes, carbon nanofibers, templated porous carbons, carbon derived carbon, carbon onion, carbon hydrogels, carbon dots, amorphous carbons and carbon foams are most widely used in EDLCs [4][5][6][7][8][9][10]. Currently carbon-based materials are being employed in many energy-related applications because of their abundance, chemical and thermal stability and processability [4].…”

“…The activated carbon was preferred over CNTs, MOFs, carbides and graphene, as later materials follow complicated, time-consuming and costly methodologies that restrict their large-scale application, regardless of containing higher surface area value with controllable pore structure and having high chemical stability [208]. On the other hand, graphene has very low volumetric capacitance value of less than 40 F/cm 3 , in comparison to that of 60 F/cm 3 from activated carbon [209][210][211][212]. Chemical doping was an effective way to change the electronic and surface chemical properties of ACs [213].…”

In recent years, heteroatom-incorporated specially structured metal-free carbon nanomaterials have drawn huge attention among researchers. In comparison to the undoped carbon nanomaterials, heteroatoms such as nitrogen-, sulphur-, boron-, phosphorous-, etc., incorporated nanomaterials have become well-accepted as potential electrocatalysts in water splitting, supercapacitors and dye-sensitized solar cells. This review puts special emphasis on the most popular synthetic strategies of heteroatom-doped and co-doped metal-free carbon nanomaterials, viz., chemical vapor deposition, pyrolysis, solvothermal process, etc., utilized in last two decades. These specially structured nanomaterials’ extensive applications as potential electrocatalysts are taken into consideration in this article. Their comparative enhancement of electrocatalytic performance with incorporation of heteroatoms has also been discussed.

The characteristics of spark ignition with a constant volume combustion chamber (CVCC) is evaluated for the efficiency of capacitive-assisted ignition (CAI), such as spark kernel and flame growth. The conventional spark method and matching effect of high voltage (MEHV) method are evaluated to compare the spark growth distribution characteristics. To do this study, a plasma system is used and is consisted of input power, three capacitors, a transformer, high voltage cable, J-type of a spark plug, diode, and CVCC. The experiment is conducted under various operating conditions, such as 1 bar, 295 K of initial temperature, 50, 100, 150 V of ignition box, 400 V of MEHV, 0.7 ms of spark duration, and 0 kΩ of plug resistor. The results show that the spark growth at the initial voltages of 100 V and 150 V has the same characteristic, and the surface area is increased by 13 mm2 at 150 V compared to 100 V because capacitance energy stored in three capacitors is efficiently induced by the effect of dielectric breakdown and electron collision. Consequently, the spark growth of MEVH is widely distributed atmospheric more than the conventional spark, and the internal temperature of the spark kernel could be presumed to change the non-thermal plasma to thermal plasma by MEHV.
