Molten NaCl-induced MOF-derived carbon-polyhedron decorated carbon-nanosheet with high defects and high N-doping for boosting the removal of carbamazepine from water

Abstract

The efficient removal of endocrine-disrupting pollutants (EDCs) from water is a crucial issue for improving the quality of drinking water.

Recent Advances on the Aqueous Phase Adsorption of Carbamazepine

“…It was observed by Chen et al. 100, that the adsorption capacity of CBZ on hierarchical structures carbon composites increased slightly with increasing pH and remained moderately stable between pH 5 and 12, indicating that the carbon composites maintained high adsorption capacities (> 200 mg g −1 ) 103…”

“…Most of the experiments were conducted at room temperature. According to Chen et al [100] the initial concentration of CBZ increases as the removal efficiency decreases albeit this is dependent on the adsorbent used and other parameters like pH and dosage. The highest adsorption capacity recorded was 316 mg g -1 at 20 mg L -1 initial concentration for single-walled CNTs [101] while the lowest adsorption capacity is 0.043 at a neutral pH of 7.0 using an initial concentration of 9.0 mg L -1 at room temperature for hexagonal mesoporous silicate adsorbent [102].…”

A review of sodium chloride-based electrolytes and materials for electrochemical energy technology

“…[60][61][62][63] Beyond that, NaCl with a clear melting point (801 C) and boiling point (1465 C) and excellent thermal stability can realize the melting state at high temperature and is considered to be an ideal molten salt agent for the molten salt method originally used to grow single-crystals. [64][65][66][67][68] In recent years, the NaCl-based molten salt method has been gradually extended to the eld of preparation of micronano electrode materials with porous or hollow structures using nanoparticles, nanosheets and nanowires as building blocks. [69][70][71][72][73] Also, the solubility of NaCl in different solutions, the clear melting and boiling points of NaCl and the coordination between NaCl and other ions can be assembled into a series of NaCl-based liquid-liquid interfaces, gas-liquid interfaces, liquid-solid interface, solid-solid interfaces, which show the unique optical and electrical properties and promote the development of electrochemical energy storage and conversion technology.…”

Designing Tubular Architectures Composed of Hollow N‐Doped Carbon Polyhedrons for Improved Supercapacitance

“…Metal–organic frameworks (MOFs) as emerging materials possess well‐defined topology, tunable composition, adjustable porous structures, and extremely high surface area. They are typically synthesized using wet‐chemical methods and have been adopted as self‐templates for the subsequent conversion to a number of porous nanostructures, such as ant‐nest‐like hierarchical carbon, [ 17 ] nanocages, [ 18 ] nanorod, [ 19 ] hollow spheres, [ 20 ] nanoparticle, [ 21 ] and hollow polyhedrons, [ 22,23 ] nanosheets [ 24 ] by thermal annealing. Very recently, a general polarity‐induced approach was developed by our group for constructing coaxial 1D structures by decorating a sheath of MOF nanocrystals (e.g., nanowires, polyhedrons, and nanoflakes) on polyacrylonitrile (PAN) nanofibers.…”
