“…The size and shape of the nano-carbon nanozymes is the key factor that affect and enhance the catalytic performance. 31,86 The specific activity of the nanozymes is significantly dependent on the nano-carbon size and morphology. The adsorption of the analytes and reactant species is the first step in enzymatic reactions.…”

“…Subsequently, the permeation flux recovered to varying degrees and remained slightly constant after rinsing with pure water. Finally, the flux recovery was measured to investigate the antifouling performance of the prepared membranes 74,75 . The GO and PSBMA@GO type membranes did not show a significant difference in terms of flux recovery ratios 76,77,79 .…”

N-(3-sulfopropyl)-N-(methacryloxyethyl)-N,N-dimethylammonium betaine (SBMA) modified graphene oxide composite used as a filler in the fabrication of a nanocomposite cellulose acetate membrane was grafted through reverse atom transfer radical polymerization (RATRP) technique from a GO-Br precursor. All the prepared materials (GO, GO-Br, PSBMA@GO) were characterized using a combination of FTIR, BET, TEM, TGA, RAMAN, and XRD. The effect of different GO and PSBMA@GO contents on cellulose acetate membranes was investigated using AFM, contact angle measurements and SEM techniques. The surface hydrophilicity of the fabricated membranes increased with increasing content of PSBMA@GO filler through the water contact angle method. The relative flux of the base membrane at 900 kPa was 66.6 L.m À2 . h À1 compared to that of PSBMA@GO composite membrane (0.5 wt%) at 117.67 L.m À2 .h À1 . The addition of the PSBMA@GO composites resulted in increased fouling resistance with high-flux recovery (93%) and low-overall flux decrease ratios (0.01%). Furthermore, nanocomposite membranes exhibited higher dye rejections for Congo Red (CR, 99.1% hence confirming their UF nature), methyl orange (MO, 84.2%) and methylene blue (MB, 95.3%) dyes compared with unmodified CA membranes. Overall, these nanocomposite membranes showed promising properties as potential candidates for dye removal in textile wastewater.

Membrane-based nanotechnology possesses high separation efficiency, low economic and energy consumption, continuous operation modes and environmental benefits, and has been utilized in various separation fields. Two-dimensional nanomaterials (2DNMs) with unique atomic thickness have rapidly emerged as ideal building blocks to develop high-performance separation membranes. By rationally tailoring and precisely controlling the nanochannels and/or nanoporous apertures of 2DNMs, 2DNM-based membranes are capable of exhibiting unprecedentedly high permeation and selectivity properties. In this review, the latest breakthroughs in using 2DNM-based membranes as nanosheets and laminar membranes are summarized, including their fabrication, structure design, transport behavior, separation mechanisms, and applications in liquid separations. Examples of advanced 2D material (graphene family, 2D TMDs, MXenes, metal–organic frameworks, and covalent organic framework nanosheets) membrane designs with remarkably perm-selective properties are highlighted. Additionally, the development of strategies used to functionalize membranes with 2DNMs are discussed. Finally, current technical challenges and emerging research directions of advancing 2DNM membranes for liquid separation are shared.
