“…g-C 3 N 4 (tri s -triazine) is an ideal material for membrane technologies because of its geometry and the triangular nanopores (∼3.11 Å) that exist on the 2D nanosheets, which allow for easy passage of water molecules with kinetic diameter of 2.6 Å . The g-C 3 N 4 –Ag 3 PO 4 -polyvinylidene fluoride, g-C 3 N 4 –Fe(OH) 3 -Al 2 O 3 , and g-C 3 N 4 –CNTs–GO–TiO 2 nanofiltration membranes, g-C 3 N 4 –Ag 3 PO 4 -poly(ether sulfone) microfiltration membranes, and g-C 3 N 4 –Ag–nafion ultrafiltration membranes exhibit improved fouling resistance, photocatalytic degradation efficiency, antibacterial activity, stability, reusability, and water flux. For example, the g-C 3 N 4 –CNTs–GO–TiO 2 nanofiltration membranes exhibit enhanced water flux (∼16 L/m 2 /h/bar) while maintaining an increased dye (∼100% for methyl orange) and salt (67% for Na 2 SO 4 ) rejection efficiency.…”

Nanotechnology has unprecedentedly revolutionized human societies over the past decades and will continue to advance our broad societal goals in the coming decades. The research, development, and particularly the application of engineered nanomaterials have shifted the focus from "less efficient" single-component nanomaterials toward "superior-performance", nextgeneration multifunctional nanohybrids. Carbon nanomaterials (e.g., carbon nanotubes, graphene family nanomaterials, carbon dots, and graphitic carbon nitride) and metal/metal oxide nanoparticles (e.g., Ag, Au, CdS, Cu2O, MoS2, TiO2, and ZnO) combinations are the most commonly pursued nanohybrids (carbon-metal nanohybrids; CMNHs), which exhibit appealing properties and promising multifunctionalities for addressing multiple complex challenges faced by humanity at the critical energy-water-environment (EWE) nexus. In this frontier review, we first highlight the altered and newly emerging properties (e.g., electronic and optical attributes, particle size, shape, morphology, crystallinity, dimensionality, carbon/metal ratio, and hybridization mode) of CMNHs that are distinct from those of their parent component materials. We then illustrate how these important newly emerging properties and functions of CMNHs direct their performances at the EWE nexus including energy harvesting (e.g., H2O splitting and CO2 conversion), water treatment (e.g., contaminant removal and membrane technology), and environmental sensing and

“…Besides coating with nanosized photocatalysts, self-cleaning conventional MMM and TFN were reported to also employ LDH and BP in contrast to the more frequently reported gCN(H) [ 220 , 221 , 222 , 223 ]. The laminar structure of the bulk material of phosphorene is that of black phosphorus, which was immersed in SPEEK membranes.…”

2D Nanocomposite Membranes: Water Purification and Fouling Mitigation

et al. 2020

View full text Add to dashboard Cite

In this study, the characteristics of different types of nanosheet membranes were reviewed in order to determine which possessed the optimum propensity for antifouling during water purification. Despite the tremendous amount of attention that nanosheets have received in recent years, their use to render membranes that are resistant to fouling has seldom been investigated. This work is the first to summarize the abilities of nanosheet membranes to alleviate the effect of organic and inorganic foulants during water treatment. In contrast to other publications, single nanosheets, or in combination with other nanomaterials, were considered to be nanostructures. Herein, a broad range of materials beyond graphene-based nanomaterials is discussed. The types of nanohybrid membranes considered in the present work include conventional mixed matrix membranes, stacked membranes, and thin-film nanocomposite membranes. These membranes combine the benefits of both inorganic and organic materials, and their respective drawbacks are addressed herein. The antifouling strategies of nanohybrid membranes were divided into passive and active categories. Nanosheets were employed in order to induce fouling resistance via increased hydrophilicity and photocatalysis. The antifouling properties that are displayed by two-dimensional (2D) nanocomposite membranes also are examined.

“…By immobilizing the photocatalyst into a polymer matrix, such a problem can be overcome. Several polymers have successfully been used as supports for photocatalysts, which includes polyamide, polyvinylidene fluoride (PVDF) [9][10][11], polysulfone (PS) [12,13], polyethersulfone (PES) [14,15], polyurethane (PU) [16,17], and polyacrylonitrile (PAN) [18][19][20].…”

In the present study, we explored the effectiveness of PES-Ag3PO4/g-C3N4 film photocatalyst in degrading methyl orange dye under visible light irradiation. The PES-Ag3PO4/g-C3N4 film photocatalyst was prepared via a non-solvent-induced phase inversion process and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), laser scanning microscopy (LSM), X-ray photoelectron spectra (XPS), UV-diffuse reflectance (DRS), and water contact angle. The incorporation of the Ag3PO4/g-C3N4 composite into the PES matrix improved the pristine PES film’s hydrophilicity, as evidenced by the reduction of water contact angle from 79.03° to 54.33° for a film containing 15 wt % of Ag3PO4/g-C3N4 composite. The film’s photoactivity showed that 13 wt % was the best loading of Ag3PO4/g-C3N4 composite, and the degradation performance was maintained up to three cycles. The •O2− and h+ were the predominant species responsible for the methyl orange degradation.
