β-Cyclodextrin modified graphitic carbon nitride for the removal of pollutants from aqueous solution: experimental and theoretical calculation study

Abstract

The enhanced interaction of β-cyclodextrin modified graphitic carbon nitride (g-C3N4/β-CD) or g-C3N4 with methyl orange (MO) or Pb(ii) in natural environmental remediation.

β‐cyclodextrin modified g‐C3N4 nanosheet: a fluorescent drug carrier with ultrahigh drug loading capacity and pH‐responsive release

“…It is noteworthy that the amine band of β‐CD/g‐C 3 N 4 shows an obvious blue shift compared with that of the pristine g‐C 3 N 4 which may be ascribed to the hydrogen bond formed between O‐H of β‐CD and N‐H of g‐C 3 N 4 . This result is consistent with Zou's study …”

“…Graphite carbon nitride (g-C 3 N 4 ), a new type of inorganic free-metallic fluorescent material, has been widely investigated in bioimaging 5,6 and biosensing 7-10 due to its unique features of good biocompatibility, low cost, simple preparation and low toxicity. 11,12 Interestingly, it is reported that the g-C 3 N 4 exhibited a pH-responsive drug release which can accelerate the release of drugs in acidic environments, while releasing less drugs in alkaline and neutral environments and thus can realize targeted therapy. Unfortunately, the reported drug release ratio of g-C 3 N 4 nanosheet was only 41.4% which will lead to the waste of drug and difficulty reaching an effective concentration.…”

One-pot synthesis of carbon supported calcined-Mg/Al layered double hydroxides for antibiotic removal by slow pyrolysis of biomass waste

“…The pseudo-first-order and pseudo-second-order models were applied to simulate the experimental kinetic data323334. Detailed information of those models is described in the Supplementary data.…”

“…The adsorption equilibrium isotherms was studied using four adsorption isothermal models including Langmuir, Freundlich, Tempkin and BET models (described in the Supplementary data) to fit the experimental data323334. The Langmuir model assumes that a monomolecular layer is formed when adsorption takes place without any interaction between the adsorbed molecules.…”

Functionalized Graphene-Based Materials as Innovative Adsorbents of Organic Pollutants: A Concise Overview

“…In this sense, the presence of aromatic rings in the adsorbate molecule contributes highly to π−π interactions with graphenebased adsorbents. Hydrogen bonds and electrostatic interactions are the dominant heteroaggregation mechanism of GO with layered double hydroxides and oxides, such as TiO 2 , MgO, ZnO, and positively charged mineral clays (Wang et al, 2017e;Wang et al, 2016a;Zou et al, 2016b). Moreover, electrostatic interactions govern the adsorption of ionic species, such as metals and some small dyes, which frequently are used in their ionized form.…”
