“…A recent report indicated that the G band represents the graphitization degree of materials, structural defects are reflected by the D band [31]. To our best knowledge, the ID/IG ratio represents structural disorder in graphitic materials [32]. As observed from Figure 3a, the value of NSG (1.09) was lower than that of SG (1.15) and NG (1.29), indicating the increasing graphitic degree of NSG which may be derived from the "self-repairing" of intermediate products under experimental conditions with the repairing of partial sp 2 -bonded C atoms.…”

Carbon nanomaterials are potential materials with their intrinsic structure and property in energy conversion and storage. As the electrocatalysts, graphene is more remarkable in electrochemical reactions. Additionally, heteroatoms doping with metal-free materials can obtain unique structure and demonstrate excellent electrocatalytic performance. In this work, we proposed a facile method to prepare bifunctional electrocatalyst which was constructed by nitrogen, sulfur doped graphene (NSG), which demonstrate superior properties with high activity and excellent durability compared with Pt/C and IrO2 for oxygen reduction (OR) and oxygen evolution (OE) reactions. Accordingly, these phenomena are closely related to the synergistic effect of doping with nitrogen and sulfur by rationally regulating the polarity of carbon in graphene. The current work expands the method towards carbon materials with heteroatom dopants for commercialization in energy-related reactions.

“…Non-graphitizable carbon with a disordered (pseudographite) structure along its c-axis is referred to as HC. 34 The HC has a structure with synthetically controllable properties and high porosity, and it can be derived from biomass, 108 pyrolyzed sucrose, 109 and phenolic cured resins. 110 The structures of HC are cross-linked to maintain its amorphous structure and prevent the development of a graphitic structure.…”

Li-ion batteries (LIBs) are being used extensively in a wide range of applications owing to the facile preparation technology as well as a high energy density, which exceeds those of other commercial batteries. However, LIBs alone cannot satisfy the burgeoning energy demand due to Li-resource constraints.Recently, K-ion batteries (KIBs) have garnered the interest of the scientific community as promising alternatives for LIBs due to the abundance of K resources, the affordability of K, and its superior electrochemical properties. However, the development of KIBs is hindered by the slow development of appropriate anode materials that can accommodate the repeated intercalation/ deintercalation of large K ions without sustaining significant structural damage. Thus, the development of appropriate anode materials is crucial for the realization of practically viable KIBs. Carbon nanomaterials are promising anode materials due to their remarkable potassiation/depotassiation ability, structural stability, and structural evolution from zero to three dimensions. It is anticipated that an evaluation of the recent advances in carbon and their composites anode materials for KIBs can facilitate the development of practically viable KIBs. This review comprehensively discusses recent developments in carbonaceous and their composites as anode materials for KIBs and provides a prospective for the next research step.

Owing to the low potential (vs K/K+), good cycling stability, and sustainability, carbon‐based materials stand out as one of the optimal anode materials for potassium‐ion batteries (PIBs). However, achieving high‐rate performance and excellent capacity with the current carbon‐based materials is challenging because of the sluggish reaction kinetics and the low capacity of carbon‐based anodes. The doping of nitrogen proves to be an effective way to improve the rate performance and capacity of carbon‐based materials as PIB anode. However, a review article is lacking in systematically summarizing the features and functions of nitrogen doping types. In this sense, it is necessary to provide a fundamental understanding of doped nitrogen types in nitrogen‐doped(N‐doped) carbon materials. The types, functions, and applications of nitrogen‐doped carbon‐based materials are overviewed in this review. Then, the recent advances in the synthesis, properties, and applications of N‐doped carbon as both active and modification materials for PIBs anode are summarized. Finally, doped nitrogen's main features and functions are concluded, and critical perspectives for future research in this field are outlined.
