High performance internally pressurized hollow fiber thin-film nanocomposite nanofiltration membrane incorporated with tannic acid functionalized MoS2 nanosheets for wastewater treatment

Tannic Acid-Functionalized MoS2 and g-C3N4 Thin Film Lamellar Membranes for Improved Permeance and Rejection in Nanofiltration

“…S 2p peaks in the spectra of both TFN-2 and TFNT-2 membranes (Figure b) appeared to be shifted toward higher binding energy, possibly regaining their lost energy during MCT formation. The S 2p 3/2 peak of MC had reduced to 161.2 from 161.6 eV upon functionalization with TA. , Now, on membrane formation, it increased back to 161.6 eV, clearly indicating the reduced interaction of MoS 2 with TA when induced into membranes.…”

“…The plot in Figure S8d represents the O 1s spectrum of TFC and additive membranes. The peaks at 531.7 and 532.8 eV are purely due to CO and C–O of amide and its hydrogen-bonded analogue in TFC . A decrease in the binding energy of the CO group to 531.3 eV for the additive membrane indicates the decreased polarity induced by nanofillers.…”

S9a depicts the measured water contact angle (WCA) of TFC and TFN membranes.…”

“…43 The plot in Figure S8d and 532.8 eV are purely due to C�O and C−O of amide and its hydrogen-bonded analogue in TFC. 44 A decrease in the binding energy of the C�O group to 531.3 eV for the additive membrane indicates the decreased polarity induced by nanofillers. Peaks due to oxygen interaction with Mo and S could not be identified separately and must have been overlapped.…”
