“…The CV curve of BNPCM in Fig. 6a exhibited redox peak, which was due to the pseudo-capacitive property of heteroatom N and B [35,47]. The B and N groups in the electrode occurred the following redox reactions.…”

“…3a) and the average pore size in Table 1. The micropores provided a larger speci c surface area for ion adsorption and mesoporous pores provided a more favorable channel for ion transport [32,33], which provide a highly speci c surface area of as high as 2333.5 m 2 g -1 , more higher than those of relevant materials reported [30,35,45,60]. The pore size distributions images showed that BNPCM contained the most micropores and small mesopores, proving that BNPCM could provide a large number of attachment sites for electrolyte ions and possessed low ion conduction resistance, which were important determinants of speci c capacitance [45].…”

“…The latter is to enrich the electrode materials of double-layer capacitor, such as heteroatom doping, adjusting the surface shape and etching of carbon materials [25][26][27][28][29][30][31]. Many researchers have explored this method, such as B, O and N co-doped biomass derived graded porous carbon (382.5 F g -1 at 1 A g -l ) [60], the preparation of the B doped wood derived porous carbon (285.6 F g -1 at 1 A g -1 ) [49], and N doped biomass carbon (261 F g -1 at 0.5A g -1 ) [35] exhibited no special morphological characteristics, leading to a relatively low speci c surface area and thus a low contribution rate of the pseudocapacitance [32][33][34]. Furthermore, the advantages of B or N element were not fully exploited.…”

The optimization of supercapacitive properties in carbon materials derived from cheap and sustainable wood scrap exhibits great application potential. Herein, in support of interfacial groups, polyaniline nanospheres were in-situ constructed in the internal pore structure of wood scraps, further the B and N element were imported by carbonized and hydrothermal. The doped B regulated the species of N-doping to improve the electrical conductivity of carbonized wood scraps, and endowed a certain pseudo-capacitance. Coupled with the fine double-layer capacitance from the hierarchical structures constructed by carbonized nanospheres and wood scrap channels, high specific capacitance of 406 F g-1 at 0.5 A g-1, high energy density (17.71 Wh kg-1 at 250 W kg-1) and cycle stability (93.04% capacitance retention after 10000 cycles) performed simultaneously. This study provided a new strategy to improve the supercapacitive performance of bio-carbon materials in terms of structure and conductance.

The incorporation of heteroatoms into carbon aerogels (CAs) can lead to structural distortions and changes in active sites due to their smaller size and electronegativity compared to pure carbon. However, the evolution of the electronic structure from single‐atom doping to heteroatom codoping in CAs has not yet been thoroughly investigated, and the impact of codoping on potassium ion (K+) storage and diffusion pathways as electrode material remains unclear. In this study, experimental and theoretical simulations were conducted to demonstrate that heteroatom codoping, composed of multiple heteroatoms (O/N/B) with different properties, has the potential to improve the electrical properties and stability of CAs compared to single‐atom doping. Electronic states near the Fermi level have revealed that doping with O/N/B generates a greater number of active centers on adjacent carbon atoms than doping with O and O/N atoms. As a result of synergy with enhanced wetting ability (contact angle of 9.26°) derived from amino groups and hierarchical porous structure, ON‐CA has the most optimized adsorption capacity (−1.62 eV) and diffusion barrier (0.12 eV) of K+. The optimal pathway of K+ in ON‐CA is along the carbon ring with N or O doping. As K+ storage material for supercapacitors and ion batteries, it shows an outstanding specific capacity and capacitance, electrochemical stability, and rate performance. Especially, the assembled symmetrical K+ supercapacitor demonstrates an energy density of 51.8 Wh kg−1, an ultrahigh power density of 443 W kg−1, and outstanding cycling stability (maintaining 83.3% after 10,000 cycles in 1 M KPF6 organic electrolyte). This research provides valuable insights into the design of high‐performance potassium ion storage materials.

“…Among all carbon [ 54,55 ] and graphene [ 56 ] doped derivatives, hybrid boron carbon nitride (BCN) materials stand out as promising substrates for a wide variety of applications [ 160 ] where they are expected to lead to cheaper, better‐performing, and non‐metallic alternatives to existing technologies. The reason why BN doping of graphene (or, vice‐versa , carbon doping of h‐BN) appears to be so promising compared to other types of doping relies on the high similarity of the two frameworks that allow for seamless integration between them.…”

The past decade has marked a renewed interest in borazines and BN‐doped polycyclic aromatic hydrocarbons. This is predominantly because of new advances that have highlighted their potential in various applications, including gas separation and storage, organic (opto)electronics, catalysis, and as supramolecular systems. This review gives a critical overview of the most significant approaches to the synthesis of (substituted) B3N3 motifs and focuses on the discussion of those borazine‐doped carbon structures that have been developed for potential use in materials science applications.
