“…This might be attributed to instrumental noise or contamination. Peaks at 1382 and 1318 cm -1 correspond to Zn-O stretching vibrations, characteristic of zinc oxide compounds, confirming the presence of zinc oxide in the material [34]. Herein, the presence of nitrogen-containing functional groups, indicated by the 3179 cm⁻¹ peak, suggests that aloe vera extracts may have played a role in the synthesis process, potentially contributing to the stabilization and unique properties of the ZnO nanoparticles.…”

Zinc oxide nanoparticles (ZnO NP) are well-known for their efficacy as inorganic compounds with antifouling and antibacterial properties in membrane filtration. In this work, bio-zinc oxide nanoparticles (bio-ZnO NP) was synthesized using Aloe vera (Aloe barbadensis miller) powder as a green reducing agent and Zinc nitrate as a precursor through the sol-gel method. Subsequently, the bio-ZnO NP powder was incorporated into a polysulfone (PSf) membrane at varying weight percentages (0.1, 0.3, 0.5, and 1.0 Wt.%). The results indicate that the addition of bio-ZnO NP to PSf enhances the size and complexity of finger-like structures, leading to an increase in tensile strength from 31.9 MPa to 57.6 MPa. However, porosity also increases from 44.1% to 58.2% as the bio-ZnO/NP content rises from 0.1 wt.% to 0.5 wt.%. Notably, the PSf/bio-ZnO NP membrane with 0.5 wt.% concentration demonstrates the highest Pure Water Flux (PWF) at 517.9 LMH with humic acid rejection reaching 99.9%. Furthermore, the incorporation of bio-ZnO NP significantly enhances antibacterial activity, as reflected in the inhibition ring diameter increasing from 24.2 mm to 48.3 mm with higher bio-ZnO/NP concentrations. The PSf/bio-ZnO NP mixed matrix membrane (MMM) with 0.3 wt.% concentration exhibits optimal stability conditions, and superior antifouling properties, making it a promising candidate for membrane applications.

“…Among them, MoS 2 provides clean 2D nanochannels that have low deficiencies or natural intercalation compared to other 2D materials. This allows it to be used for the desalination of dye as well as sea and brackish water 56–61. Several studies also demonstrated the high efficiency of MoS 2 membranes for small ions, dyes, and other water pollutants (Tab.…”

Molybdenum sulfide (MoS2)‐based nanocomposites have attracted significant attention for various separation processes due to their ultrathin thickness, high mechanical and chemical strength, and good functionality. Herein, the recent progresses of various fabrication, synthesis, and modification methods for separation membrane‐based on MoS2 nanocomposites are reviewed. Emphasis is given on applications of MoS2‐based membranes in the purification of wastewater, separation of gas mixtures, energy storage separator, and proton‐exchange fuel cells (PEFCs). Advantages and drawbacks of this material for separation applications are discussed. Finally, a future roadmap is suggested for this promising nanomaterial in various separation processes.
