“…Notably, porous carbons acquired a high diversity of structural pores such as micropores with pore size lower than 2 nm, mesopores with pore size between 2 and 50 nm, and macropores with pore size lower than 50 nm (Wang et al 2020 ). Porous carbons with micro-sizes or meso-sizes may be conducive for the adsorption of small molecules, especially antibiotics (Zhang et al 2021a , b , c , d ). Furthermore, the porosity of porous carbon can be flexibly driven by the activation temperature (Bi et al 2019 ).…”

“…Referring to thermodynamic parameters, the spontaneity and heat of chloramphenicol adsorption over the adsorbent can be better understood (Chen et al 2021 ; Dai et al 2018a ). Characteristic parameters affecting the process involve Gibbs free energy , enthalpy , and entropy (Yang et al 2020a , b ; Zhang et al 2021a , b , c , d ). Mathematically, they are originated from classical Van 't Hoff expression, represented by the following equations (Eqs.…”

“…For example, the exothermic nature of the chloramphenicol uptake over both metal–organic framework Fe 3 O(BDC) 3 and mesoporous carbon was described because was lower than zero (Tran et al 2019a ). Considering the thermodynamic data of the chloramphenicol adsorption over powdered activated carbon, Zhang et al, ( 2021a , b , c , d ) found a thermodynamically nonspontaneous process because was higher than zero. Moreover, negative values of were overwhelmingly dominant in some chloramphenicol adsorption systems using metal–organic framework and raw steel shavings (Tran et al 2017 , 2019a ).…”

“…The exposure of chloramphenicol possibly causes some serious impacts on the environment and human health (Sall et al 2020 ). For aquatic organisms, chloramphenicol has a high level of ecological toxicity (Zhang et al 2021a , b , c , d ). This compound inhibits the growth and development of green algae (Xiong et al 2019 ), blue-green algae (Xiong et al 2019 ), marine algae, and freshwater green alga (Parthasarathy et al 2020 ) through specific protein control (Holanda et al 2019 ).…”

For animals, e.g., rat, cat, dog, and pig and humans, chloramphenicol is known to be a contributing factor in the aplastic anemia (Zhang et al 2021a , b , c , d ). This disease relates to deficiencies in producing red and white blood cells, leading to blood disorder, and high mortality rate (Cao et al 2020 ).…”

Chloramphenicol is a broad-spectrum bacterial antibiotic used against conjunctivitis, meningitis, plague, cholera, and typhoid fever. As a consequence, chloramphenicol ends up polluting the aquatic environment, wastewater treatment plants, and hospital wastewaters, thus disrupting ecosystems and inducing microbial resistance. Here, we review the occurrence, toxicity, and removal of chloramphenicol with emphasis on adsorption techniques. We present the adsorption performance of adsorbents such as biochar, activated carbon, porous carbon, metal–organic framework, composites, zeolites, minerals, molecularly imprinted polymers, and multi-walled carbon nanotubes. The effect of dose, pH, temperature, initial concentration, and contact time is discussed. Adsorption is controlled by π–π interactions, donor–acceptor interactions, hydrogen bonding, and electrostatic interactions. We also discuss isotherms, kinetics, thermodynamic data, selection of eluents, desorption efficiency, and regeneration of adsorbents. Porous carbon-based adsorbents exhibit excellent adsorption capacities of 500–1240 mg g −1 . Most adsorbents can be reused over at least four cycles.

Here, a novel fabrication method for making free‐standing 3D hierarchical porous carbon aerogels from molecularly engineered biomass‐derived hydrogels is presented. In situ formed flower‐like CaCO3 molecularly embedded within the hydrogel network regulated the pore structure during in situ mineralization assisted one‐step activation graphitization (iMAG), while the intrinsic structural integrity of the carbon aerogels was maintained. The homogenously distributed minerals simultaneously acted as a hard template, activating agent, and graphitization catalyst. The decomposition of the homogenously distributed CaCO3 during iMAG followed by the etching of residual CaO through a mild acid washing endowed a robust carbon aerogel with high porosity and excellent electrochemical performance. At 0.5 mA cm−2, the gravimetric capacitance increased from 0.01 F g−1 without mineralization to 322 F g−1 with iMAG, which exceeds values reported for any other free‐standing or powder‐based biomass‐derived carbon electrodes. An outstanding cycling stability of ~104% after 1000 cycles in 1 M HClO4 was demonstrated. The assembled symmetric supercapacitor device delivered a high specific capacitance of 376 F g−1 and a high energy density of 26 W h kg−1 at a power density of 4000 W kg−1, with excellent cycling performance (98.5% retention after 2000 cycles). In combination with the proposed 3D printed mold‐assisted solution casting (3DMASC), iMAG allows for the generation of free‐standing carbon aerogel architectures with arbitrary shapes. Furthermore, the novel method introduces flexibility in constructing free‐standing carbon aerogels from any ionically cross‐linkable biopolymer while maintaining the ability to tailor the design, dimensions, and pore size distribution for specific energy storage applications.

Aromatic biomass (torch ginger) leaf‐derived three‐dimensional honeycomb‐like carbon to enhance gravimetric supercapacitor

et al. 2023

View full text Add to dashboard Cite

BackgroundPorous carbon electrode (PCE) is identified as a highly suitable electrode material for commercial application due to its production process, which is characterized by simplicity, cost‐effectiveness and environmental friendliness. PCE was synthesized using torch ginger (Etlingera elatior (Jack) R.M. Smith) leaves as the base material. The leaves were treated with different concentrations of ZnCl2, resulting in a supercapacitor cell electrode with unique honeycomb‐like three‐dimensional (3D) morphological pore structure. This PCE comprises nanofibers from lignin content and volatile compounds from aromatic biomass waste.ResultsFrom the characterization of physical properties, PCE‐0.3 had an impressive amorphous porosity, wettability and 3D honeycomb‐like structural morphology with a pore framework consisting of micropores and mesopores. According to the structural advantages of 3D hierarchical pores such as interconnected honeycombs, PCE‐0.3 as supercapacitor electrode had a high specific capacitance of up to 285.89 F g−1 at 1 A. Furthermore, the supercapacitor exhibited high energy and power density of 21.54 Wh kg−1 and 161.13 W kg−1, respectively, with a low internal resistance of 0.059 Ω.ConclusionThe results indicated that 3D porous carbon materials such as interconnected honeycombs derived from the aromatic biomass of torch ginger leaves have significant potential for the development of sustainable energy storage devices. © 2023 Society of Chemical Industry.
