“…Moreover, it is well known that wood is mainly composed of cellulose, hemicellulose, and lignin. [ 21 ] The corresponding structures of cellulose, hemicellulose and lignin are displayed in Figure S12 (Supporting Information). [ 22 ] Combined with evolution of high‐temperature hydrothermal products, the following reaction mechanism for OCMS and 3DPC can be obtained.…”

The comprehensive utilization of biomass to obtain energy-storage carbonaceous materials with special microstructures is of great significance. Herein, a universal method is proposed to fabricate oriented carbon microspheres (OCMSs) and 3D porous carbon (3DPC) block at the same time via high-temperature hydrothermal "disproportionation" of biomass including but not limited to basswood, pinus sylvestris, red walnut, beech, bamboo, and sorghum straw. Through nuclear magnetic resonance, gas chromatography mass spectrometry, as well as various morphologic and structural characterizations, it is demonstrated that OCMS with (002) orientation originates from the carbonization of organic matters produced by the successive decomposition of hemicellulose, cellulose, and lignin during the high-temperature hydrothermal process, while the 3DPC blocks exhibit abundant sp 3 defects and micropores with a surface area of 855.12 m 2 g −1 due to the constant loss of organic components from basswood blocks. As a result, the OCMS anode exhibits a high capacity of 201.1 mA h g −1 at 2000 mA g −1 after 2000 cycles, 3DPC cathode delivers a capacity of 95.7 mA h g −1 at 1.0 A g −1 after 5000 cycles. Remarkably, the as-assembled OCMS//3DPC potassium ion hybrid capacitor exhibits an energy of 140.7 Wh kg −1 at 643.8 W kg −1 , with a long cycle life over 8500 cycles.

“…Other biomass with high SSA can be converted into 3D BCMs or carbon aerogel directly, which show the same ability of separation, for instance, catkins [306] wood, [307] bacterial cellulose, [308] and natural cotton. [73] Carbon dots and 0D BCMs own many outstanding properties, including excitation-dependent emission, high water solubility, excellent photostability, easy surface functionalization, good biocompatibility, and low toxicity, making them promising for bioimaging and biosensing, [309][310][311] light-emitting, [312][313][314][315] drug delivery, [316][317][318][319] and photocatalysis and optoelectronics. The CDs usually consist of two parts: the carbon core, which is composed of graphitized carbon with few defects and modified groups, and the functional shell, which is formed through hybridization of the carbon backbone and has attached chemical groups.…”

Biomass‐derived carbon materials (BCMs) are encountering the most flourishing moment because of their versatile properties and wide potential applications. Numerous BCMs, including 0D carbon spheres and dots, 1D carbon fibers and tubes, 2D carbon sheets, 3D carbon aerogel, and hierarchical carbon materials have been prepared. At the same time, their structure–property relationship and applications have been widely studied. This paper aims to present a review on the recent advances in the controllable preparation and potential applications of BCMs, providing a reference for future work. First, the chemical compositions of typical biomass and their thermal degradation mechanisms are presented. Then, the typical preparation methods of BCMs are summarized and the relevant structural management rules are discussed. Besides, the strategies for improving the structural diversity of BCMs are also presented and discussed. Furthermore, the applications of BCMs in energy, sensing, environment, and other areas are reviewed. Finally, the remaining challenges and opportunities in the field of BCMs are discussed.
