“…[56] The Pd (0) has more comparative valence than Pd (II) state in the Pd/BC-2 on account of the cumulative strength ratio. [57] The B1s spectrogram including the BC-1, BC-2 and BC-3 samples ( Figure 6D, 6E, 6F) can be generally deconvoluted into two peaks, which are agreement with BÀ C (191.3 eV) and BÀ O (192.5 eV) bonds.

“…The elementary analysis by XPS also suggests a correspondingly high level of boron (3.32 %) in BC-2. [57] The B1s spectrogram including the BC-1, BC-2 and BC-3 samples ( Figure 6D, 6E, 6F) can be generally deconvoluted into two peaks, which are agreement with BÀ C (191.3 eV) and BÀ O (192.5 eV) bonds. [58] The ratio of BÀ C to BÀ O content of the three BC materials is 3.16, 5.83, 4.00, suggesting that the BC-2 has the most highest ratio of BÀ C bond in the BC-1, BC-2 and BÀ C-3 supports.…”

Boron-doped carbon nanocage (BC-2) was used as carrier to anchor palladium nanoparticles and enhanced the catalytic performance for the ethanol oxidation reaction. The BC-2 was synthesized via thermal treatment the predesigned compound containing cobalt and boron at 900°C with the help of hydrogen and acid washing process. Palladium nanoparticles can be loaded on the BC-2 supports (Pd/BC-2) for ethanol oxide reaction (EOR). The BC-2 support has the following character-istics: (i) The hollow structure contains highly order nanoporous to offer more channel and space in catalysis process; (ii) borondoped carbon structures can supply abundant activity sites for stabilizing palladium nanoparticles; (iii) the unique three-dimensional architecture can prevent the agglomeration and inactivation of metal catalysts. The Pd/BC-2 catalyst displays higher catalytic activities 3614.11 mA mg À 1 toward the peak current density compared to that of Pd/C (804.39 mA mg À 1 ).

“…Doping is divided into two categories: artificial doping and self‐doping. The former is to introduce heteroatom‐doped functional groups on its surface by the post‐treatment of biomass carbon with amines,, urea,, thiourea, phosphoric acid, monoammonium phosphate or boric acid etc. For example, zhou et al .…”

As a green and effective energy storage device, supercapacitors have been attractive due to their high power density along with long cycle stability. Among various electrode materials, carbon materials have drawn significant attention due to their wonderful properties, such as high specific surface area, electronic conductivity, chemical stability and porous structures. In addition, challenges come from global warming and environmental pollution, biomass derived carbon materials feature the concepts of the sustainable development of chemistry. In this, the review not only summarizes the most advanced progress in biomass derived heteroatoms self‐doped carbon materials for supercapacitor, but also provides important guidelines for the future design of biomass‐derived carbons with heteroatoms doping in specific energy applications.

“…[13][14][15] For example, pyridinic-N, pyrrolic-N, quaternary-N and pyridinic-N-oxide are found to be the main doped-N species in N-doped carbons 16 ; four doped-S species (thiophenic sulfur, sulfoxide, sulfone and sulfonic acid) are present in S-doped carbons 17 ; quinone groups, phenolic groups and carboxyl groups as the primary O species can be generally detected in O-doped carbons 18 ; as for P-doped carbon materials, the main P species are P-C bonding, pyrophosphate and metaphosphate, 19 etc. However, it is a remarkable fact that most of the ongoing researches mainly put their insights into the e®ects of the dopant type [20][21][22][23][24] and the doping amount. [25][26][27][28] As for the possible relevance between the type of the doped species and the corresponding contribution to the capacitance, it is presently not well understood, which, undoubtedly, will be not bene¯cial to the development of technical strategy for achieving the optimal capacitive performances by means of optimizing the type of doped species.…”

O-doping has proved to be one of the most promising approaches to further enhance the supercapacitive performance of carbon materials. However, it is presently not clear how the type of doped-O species affects the capacitive performance. In this paper, an attempt has been made to probe into the possible correlation between the type of doped-O species and the corresponding capacitive performance. Three O species (C=O, C–O and O–C=O) have been introduced onto TiC-derived carbon (TiC–CDC) by using a facile room-temperature oxidation strategy with three typical oxidizing agents (H2O2, HNO3 and (NH[Formula: see text]S2O[Formula: see text], respectively. The results have shown that as the content of the C=O species increases, both the specific capacitance and the capacitance retention for the oxidized TiC–CDC samples become higher, showing a positively correlative performance. This work suggests that optimizing the type of doped-O species will be great potential for obtaining the optimal electrochemical performances for the O-doped carbon materials.
