“…Along with the monodoped carbon catalysts discussed above, co‐doping of carbon materials with two or more different heteroatoms can further enhance the catalytic performance of the carbon catalysts by increasing the total number of active sites and through possible synergistic effects. [ 47 ] So far, co‐doping studies have been focused on co‐doping of N‐doped carbon materials with a second element, such as B, [ 69–76 ] S, [ 77–88 ] P, [ 89–106 ] and, to a less extent, Cl, [ 107 ] and Si. [ 108,109 ] A few reports on the co‐doping of carbon materials with three elements, such as N–P–S, [ 110,111 ] N–P–B, [ 112,113 ] N–P–F, [ 114 ] and N–S–F, [ 115 ] have recently appeared.…”

Ten years have passed since the discovery of the first nitrogen‐doped carbon‐based metal‐free catalyst for the oxygen reduction reaction, which opened a new field of catalysis toward a large variety of important applications, ranging from energy conversion and storage to environmental remediation. Various heteroatom‐doped carbons, beyond nitrogen‐doping (N‐doping), with distinctive features have also been developed for many specific reactions of practical significance (e.g., oxygen reduction (ORR), water splitting (OER and HER), CO2 reduction (CO2RR), and N2 reduction (NRR)). However, the topic of metal‐free non‐N‐doped carbon electrocatalysts has not been reviewed till now. This article aims to review recent advances in non‐N‐doped carbon electrocatalysts with an emphasis on their synthesis, catalytic mechanisms, and catalytic performance in various electrochemical reactions, including the ORR, OER, HER, H2O2 production, NRR, and CO2RR. Like N‐doping, boron‐doping, phosphorus‐doping, and fluorine‐doping are found to show similar catalytic efficiency for the ORR, OER, and HER. However, oxygen‐doping and boron‐doping are particularly favorable for the selective production of H2O2 and NH3, respectively, exceeding the performance of N‐doping. Along with the timely and critical overview on the non‐N‐doped carbon electrocatalysts, current challenges and future perspectives for this emerging field are also discussed.

“…An environmental friendly, quick, economical, and efficient method has been reported for the synthesis of a co-doped material by Viswanathan and his group [172]. In this regard, highly thermally stable phosphorous and nitrogen co-doped materials were synthesized by microwave-assisted carbonization of aminated tannin.…”

Herein, metal-free heteroatom doped carbon-based materials are being reviewed for supercapacitor and energy applications. Most of these low-cost materials considered are also derived from renewable resources. Various forms of carbon that have been employed for supercapacitor applications are described in detail, and advantages as well as disadvantages of each form are presented. Different methodologies that are being used to develop these materials are also discussed. To increase the specific capacitance, carbon-based materials are often doped with different elements. The role of doping elements on the performance of supercapacitors has been critically reviewed. It has been demonstrated that a higher content of doping elements significantly improves the supercapacitor behavior of carbon compounds. In order to attain a high percentage of elemental doping, precursors with variable ratios as well as simple modifications in the syntheses scheme have been employed. Significance of carbon-based materials doped with one and more than one heteroatom have also been presented. In addition to doping elements, other factors which play a key role in enhancing the specific capacitance values such as surface area, morphology, pore size electrolyte, and presence of functional groups on the surface of carbon-based supercapacitor materials have also been summarized.

“…Lastly, codoping graphene with two types of dopants can also greatly benefit electrochemical performance [57][58][59]. For example, a novel strategy for synthesis of highly porous nitrogen-sulfur co-doped graphene nanoribbons (NS-GNRs) with enhanced active sites was developed by Gopalsamy et al [57].…”

“…In another approach using phosphorous (P) codopant, a phosphorus and nitrogen co-doped carbon material (PNDC) was synthesized from aminated tannin and polyphosphoric acid by a rapid and highly efficient microwave synthetic technique. Specific capacitance in 6 M KOH was determined to be 161 F g −1 [59]. Also, melamine phosphate, as a sole precursor, was used to synthesize nitrogen/phosphorus co-doped graphene (N/P-G) monoliths by a facile hydrothermal method.…”

Graphene-based materials in two-dimensional (2D) and three-dimensional (3D) configurations are promising as electrode materials for supercapacitors due to their large surface area, excellent electrical conductivity, high electrochemical activity and high stability. In this article recent advances in research on 2D and 3D graphene-based materials for supercapacitor electrodes are reviewed extensively in aspects of fabrication methods and electrochemical performances. From the survey, the performance of 2D and 3D graphene-based materials could be significantly enhanced by employing nanostructures of metal oxides, metals and polymers as well as doping graphene with hetero atoms such as nitrogen and boron. In addition, the charge storage performances were found to depend greatly on materials, preparation method and structural configuration. With similar material components, 3D graphene-based networks tended to exhibit superior supercapacitive performances. Therefore, future research should be focusing on further development of 3D graphene-based materials for supercapacitor applications.
