Graphene is an interesting two-dimensional carbon sheet possessing single-layered atom thickness that confers unique physical and chemical properties. The pristine graphene sheets have some limited applications in water purification, but the modification of graphene into the graphene composite by the incorporation of some functional groups or nanoparticles on the surface extensively increases its environmental applications. Recently, graphene nanocomposites have found to show very promising applications in all types of water purification. The present review highlights the recent developments in the applications of graphene and graphene-based composites as adsorbent, catalyst, photocatalyst, electrocatalyst, photoelectrocatalyst, and disinfection and desalination agent in comprehensive water purification systems. We primarily focus on the environmental engineering applications of graphene nanocomposites as sorbent materials for the elimination of toxic inorganic (cationic and anionic), organic, and mixed/multiple pollutants, and as catalysts for the degradation of toxic organic contaminants using catalytic oxidation, photocatalytic oxidation, electrocatalytic oxidation, and photoelectrocatalytic oxidation. We have also discussed the use and feasibility of graphene nanocomposites in water disinfection and desalination. Finally, the future challenges and perspectives are discussed.

“…The existence of hydrogen on MWCNT-TNT can enhance the hydrogen bonding formation in PA layer which in turn decreased the pore sizes in PA layer while later contributed to low water permeability and increase NaCl rejection [9]. Moreover, the successful synthesis of MWCNT-TNT as confirmed by XRD and TEM provides unique properties for the membrane which offers pore channels and high hydrophilicity of hybrid to increase water permeability while reject certain dissolved ions [10], [11]. Meanwhile, when the MWCNT-TNT was treated with acid (a-MWCNT-TNT) and was incorporated into the polyamide layer of TFC B, the water permeability was increased as indicated by decreasing contact angle from 72.92 to 61.71 o of the membrane as shown in Table 1.…”

In this study, thin film nanocomposite (TFN) membranes were prepared by incorporating multi-walled carbon nanotube-titania nanotube (MWCNT-TNT) hybrid into the polyamide layer via interfacial polymerization on the surface of PS35 commercial substrate. The study showed that in the neat thin film composite (TFC), the presence of PIP in polyamide layer increased the water permeability (from 0.54 to 2.25 L/m 2 h bar) but decreased the NaCl rejection (from 86.48 to 47.45%). Interestingly, the presence of MWCNT-TNT in MPD-PIP polyamide layer increased the NaCl rejection by 38.68% (47.45 to 86.13%) while giving a significant water permeability performance at 0.86 L/m 2 h bar. The incorporation of acid treated MWCNT-TNT has improved the water permeability from 0.86 to 0.89 L/m 2 h bar while decreasing the NaCl rejection from 86.13 to 77.51%. Further investigation of MWCNT-TNT loading at pH 2 revealed that the increase of its loading in polyamide layer decreased both water permeability and NaCl rejection performance of the membrane. Overall, it can be concluded that the addition of an appropriate loading of surface modified MWCNT-TNT into the polyamide layer can remarkably improve the performance of conventional TFC membranes for desalination applications. In addition, incorporating PIP in the polyamide layer reduces the capability of the membrane on NaCl rejection.

Kajian ini menunjukkan bahawa tanpa MWCNT-TNT, kehadiran PIP dalam lapisan poliamida meningkatkan kebolehtelapan air (daripada 0.54 kepada 2.25 L/m 2 h bar) tetapi mengurangkan penyingkiran NaCl (daripada 86.48 kepada 47.45%). Menariknya, kehadiran MWCNT-TNT dalam lapisan poliamida MPD-PIP meningkatkan penyingkiran NaCl pada 38.68% (47.45 kepada 86.13%) sambil memberi prestasi kebolehtelapan air yang besar pada 0.86 L/m 2 h bar. Penggabungan MWCNT-TNT ygng dirawat asid telah meningkat kebolehtelapan air dari 0.86 to 0.89 L/m 2 h bar namun mengurangkan penyingkiran NaCl (daripada 86.13 kepada 77.51%). Siasatan lanjut terhadap muatan MWCNT-TNT pada pH 2 mendedahkan bahawa peningkatan muatannya dalam lapisan poliamida menurun kedua-dua prestasi membran terhadap kebolehtelapan air dan penyingkiran NaCl. Secara keseluruhan, dapat disimpulkan bahawa penambahan muatan dan pH yang

“…However, consideration of some of the other citing journals reveals a surprising breadth of interest in the material that is published in the journal. For example: an article in Acta Alimentaria entitled "Extrusion of corn grits with native or modified starch addition -influence on starch digestibility fractions, shear stress-at-break, and expansion ratio" [3] cites a JMC article on the use of Markov chains to model non-homogeneous flows [4]; and an article in Desalination entitled "Recent applications of nanomaterials in water desalination: A critical review and future opportunities" [5] cites a JMC article modelling the transportation of sodium and chloride ions [6]. Similar behaviour is observed if one analyses the citing publications in terms of the WoS subject category to which they belong.…”
