A dual-functional layer modified GO@SiO2 membrane with excellent anti-fouling performance for continuous separation of oil-in-water emulsion

Review of New Approaches for Fouling Mitigation in Membrane Separation Processes in Water Treatment Applications

“…As the most important target of membrane separation, the inadequacy of permeability and anti-fouling frequently limits the application of the membrane in actual oily wastewater [110]. Feng et al [111] proposed a novel concept of membrane surface construction to mitigate this intractable problem, using SiO 2 as the support layer and GO as the isolation layer (Figure 18). The separation performance of the modified membranes for the simulated emulsion indicated the optimal co-localization percentage of the support layer (56 mg/L) and isolation layer (3.5 mg/L).…”

A super-hydrophilic NH2-MIL-125 composite film with dopamine-modified graphene oxide is used for water treatment

“…28,29 Strong acids are used to oxidize graphene, after which its oxygen functional groups increase, [30][31][32][33] its nature is more active, and it shows hydrophilicity. [34][35][36][37] A review of the literature shows that GO can be prepared in a variety of ways. The Hummers' method is relatively safe and it is the most commonly used method for preparing graphene oxide.…”

Agave-Angustifolia-like Cu3Mo2O9 Nanoplate-Coated Copper Mesh for Effective Emulsion Separation and Photocatalytic Degradation of Soluble Dyes

“…Surface roughness and high surface tension are the fundamental attributes of wettability-based materials for efficient oil/water separation. 21 Recently, there are multiple reports on various preparation methods and morphologies of Cu 3 Mo 2 O 9 structures, such as nanopowders, 22 nanosheets, 23 nanoplates, 24 micropompons, 17 and 3D hierarchical flowers, 25 necessary surface roughness. Additionally, like other metal oxides, it expectedly has high surface energy and intrinsic hydrophilicity.…”

“…To the best of our knowledge, there is no report about the application of copper molybdate for oil/water separation. Surface roughness and high surface tension are the fundamental attributes of wettability-based materials for efficient oil/water separation . Recently, there are multiple reports on various preparation methods and morphologies of Cu 3 Mo 2 O 9 structures, such as nanopowders, nanosheets, nanoplates, micropompons, and 3D hierarchical flowers, which makes Cu 3 Mo 2 O 9 a suitable candidate for the construction of a membrane with necessary surface roughness.…”
