“…Therefore, to determine the pore size of the GO-Fc/GO-CD membrane at different redox states, we measured the rejection of PEG with different molecular weights and estimated the pore size distribution through a probability density function model. 45 As shown in Figure 4a, the mean effective pore sizes of the GO-Fc/GO-CD membrane increased from 1.7 nm in the reduction state to 2.0 nm in the oxidation state. This result confirmed the pore size change of the GO-Fc/GO-CD membrane by regulating the membrane redox state.…”

Intelligent and controllable water and molecule transport through a membrane is of crucial significance for broadening membrane applications in smart-gating filtration. Herein, inspired by the extensive redox reactions in living systems, we report a redox-responsive graphene oxide (GO) membrane assembled by introducing a supramolecular host−guest complex between ferrocene (Fc) and β-cyclodextrin (CD) into the interlayer of GO. The well-designed intelligent responsive membrane, which was composed of Fc-modified GO and CDmodified GO, possessed fascinating redox-response property. Utilizing the reversible deformation and restoration of the Fc/ CD complex, the size of the interlayer nanochannel between adjacent GO nanosheets was tunable by changing the membrane redox state. The water permeance and molecular separation performance of the membrane could be reversibly regulated with a high gating ratio (5.6) by virtue of the redox-responsive interlayer nanochannel. In addition, the obtained membrane also demonstrated superior cyclic response performance, excellent antifouling ability, and satisfactory stability in harsh environments. This work provides an innovative strategy for the fabrication of redox-responsive membranes, showing promising applications in intelligent and controllable gating and controllable water-contaminant removal process.

“…It should be noted that the presence of other factors in the effluent from the textile industry, such as salts, as well as a wide range of dyes, separation, and water recycling operations, face many problems (Koparal et al, 2007; Mansour et al, 2011). For this reason, over the last years, many researchers have proposed many methods to solve this dilemma (Tufa et al, 2015; Werber et al, 2016), for example, electrocoagulation (Han et al, 2016), advanced oxidation process (Asghar et al, 2015), adsorption (Oveisi et al, 2018; Wang et al, 2015), and membrane separation (Guo et al, 2021; Tian et al, 2021; Zeng et al, 2022). Membrane separation processes are known as one of the cost‐effective technologies for removing dyes and contaminants from industrial effluents.…”

Facile techniques to fabricate the nanofiltration membranes with ideal molecular sieving is one of the most interesting subjects in membrane separation technology. In this study, the application of modified graphene oxide (GO) with triethylenetetramine (TETA), CuFe 2 O 4 , and acetic acid (AC) (supported GO-TETA-CuFe 2 O 4 @AC) as a supported protic ionic liquid (PIL) modifier for polyethersulfone (PES) membrane was evaluated to approve the improvement of anti-fouling properties and wastewater rejection of the fabricated membranes. To enhance the key properties of graphene oxide, it was modified by hydrophilic nanomaterials (TETA-CuFe 2 O 4 ). High flux and promising flux recovery ratio (up to 95% compared to the unmodified membrane) can be observed in the modified membranes. The modified membranes by GO-TETA-CuFe 2 O 4 @AC were studied at optimum concentrations (0.5 wt. %) for salt rejection and different dyes. The obtained data indicated that the modified membranes by GO-TETA-CuFe 2 O 4 @AC indicated higher salt removal (up to 97% for BaCl 2 than the unmodified membrane), which was related to the efficient modification. The obtained pure water flux (PWF) for bare and optimal modified membrane from 13.11 to 27.87 kg/m 2 Áh, respectively. To exact evaluate the effect of membrane modification on performance examination, the modified membranes were evaluated for chlorine resistance testing. This study aimed to develop cost-effective nanofiltration (NF) membranes with high anti-fouling properties and to determine the maximum filtration capacity of in-time dyes and salts in effluents. Practitioner Points• A GO-TETA-CuFe2O4 mixed matrix membrane was prepared for removal of salts and dyes.• The effect of GO-TETA-CuFe2O4 enhanced the hydrophilicity and porosity.• The membrane exhibited superior antifouling properties and ions rejection.
