“…Before pyrolysis at high temperature, intermediate products are usually prepared by chemical reagents, gas atmosphere, and precarbonization at low temperature. [23] Porous improvement using chemical activators is a common method because it is simple and efficient. Materials are impregnated or grinded with activators, and then heat treated to prepare porous carbon.…”

[23] According to plantcarbon structure, four categories are divided, including 0D, 1D, 2D, and 3D, as described in Figure 1. Among them, 0D carbon materials refer to spherical carbon particles with an aspect ratio of ~1 and mainly include porous carbon spheres (PCS) [24] and carbon dots (CDs).…”

The increasing demand for sodium‐ion batteries has risen due to sodium resources that are inexpensive and abundant compared with its counterpart of lithium‐ion batteries. Development of anode materials with high performance is central issue for sodium‐ion batteries. Plant‐based hard carbon material is a promising anode material for sodium ion batteries due to its green preparation process, favorable ions transport channel, and special porous structure. Previous studies have not systematically correlated the material's inherent structure limitation with its electrochemical properties, resulting in a complex classification and a lack selection of pretreatment methods. In this review, the intrinsic limitations in the structure of plant‐based precursors are divided into four parts, including impure components, single chemical structure, uncontrollable crystalline texture, and irregular porous structure. The previous pretreatment methods are reclassified, including purification component aiming at plant‐based precursors, optimized structure, and precabornized process aiming at intermediate products. Furthermore, the pretreatment strategies are discussed according to the preferred structures of plant‐based hard carbon and the relationship between structure and performance is systematically expounded. This review provides deep understanding of the mechanism of pretreatment and a guide for selecting appropriate pretreatment strategies to optimize the structure of plant‐based hard carbon for sodium ion batteries.

“…43 As a building block for electrochemical sensors, 2D carbon materials have a unique layered structure, excellent conductivity, higher specific surface area, and more abundant and accessible surface active sites than other types of carbon nanomaterials. 44 However, the applications of electrochemical sensors developed based on 2D-BC materials in environmental and big health industry have rarely been reported.…”

“…Owing to their high power densities, high energy conversion efficiencies, and tunable power volumes, proton exchange membrane fuel cells (PEMFCs) are gaining more attention in recent years to replace environmentally unfriendly and nonrenewable fossil fuels. − A proton exchange membrane (PEM), a core component in a PEMFC, should be specifically designed to be highly proton-conducting and chemically stable. Metal–organic frameworks (MOFs) exhibit great potential as proton-conducting materials because of their high crystallinity, tunable porosity, rich guest–host interactions, and designable functionality. − …”

F 2 (SO 3 H) 2 manifests a superprotonic conductivity of 2.86 S cm −1 (at 90% RH and 90 °C), a record breaker so far. Supported by joint experimental−theoretical studies, the ultrahigh conductivity originates from conduction by protons rather than ions and is rationalized to result from the enhanced acidity of −SO 3 H by introduction of electronegative −F followed by the formation of double charged layers composed of Li + and −SO 3 − layers after encapsulation of LiCl. Importantly, the effect of charged layers has been verified, and charged-layer-mediated proton conduction is unprecedentedly proposed to fill in the missing pieces in existing proton conduction mechanisms, giving insight into the rational design of superprotonic conducting framework materials potentially applied as proton exchange membranes in fuel cells.
