Synthesis, formation mechanisms and applications of biomass-derived carbonaceous materials: a critical review

Abstract

The transformation of biomass to graphene has recently attracted increasing attention because of its high carbon contents and renewable nature. Various applications of biomass-derived graphene are currently sought because of...

Natural Hollow Fiber-Derived Carbon Microtube with Broadband Microwave Attenuation Capacity

“…As shown in Figure 1 , the additive-free carbon microtube was prepared by directly carbonizing the kapok fibers in the argon atmosphere, with the designed experimental scheme of seven pyrolysis temperatures ranging from 500 °C to 800 °C. During the pyrolysis process, volatile constituents (such as CH 4 , CO 2 , and some organics) were removed, generating unique hollow microtube with numerous interior pores along the carbon skeleton [ 14 ], which is favorable for decreasing the density and boosting microwave attenuation. Among them, the carbon microtube samples with 30 wt.% loading of CKF obtained around 650 °C demonstrate the optimized MA performance, with an RL min of −62.46 dB for CKF-650 and an EAB of 6.80 GHz for CKF-600, which is competitive with those of most MA materials reported previously.…”

“…Owing to their renewable, eco-friendly, and abundant resources, biological-organisms-derived porous carbon materials have been extensively investigated and widely used in energy storage, catalysts, and pollutant adsorbents [ 13 , 14 , 15 ]. Similar to other man-made porous materials, it is promising to use bio-inspired microstructure to fabricate microwave absorbers because long-term evolution endows biomass with many unique features including hierarchical texture, periodic pattern, and distinct nanoarchitecture [ 16 , 17 , 18 ].…”

Biomass-derived porous carbon materials: synthesis, designing, and applications for supercapacitors

“…Therefore, the use of biomass for the production of activated carbon for supercapacitor electrodes is considered an effective way to solve the problem of agricultural or domestic waste disposal. 46 These days, the use of biomass for the formation of activated electrode materials for the electrochemical energy storage field has attracted much interest. [47][48][49][50] This review is to highlight the recent advances in biomass-derived porous carbon materials: synthesis, designing, and application for supercapacitors (Fig.…”

Hydrodynamic cavitation-assisted preparation of porous carbon from garlic peels for supercapacitors

“…Since they naturally possess many beneficial functional groups and heteroatoms, and properties of extensive access and sustainability, these BDCMs have large potential for commercial SCs [23] , [24] . To achieve high specific capacitance, a high specific surface area is needed [25] . Therefore, it is necessary to activate the source carbons in physical or chemical ways before utilizing them in SCs.…”
