Recent Progress in Superhydrophilic Carbon-Based Composite Membranes for Oil/Water Emulsion Separation

Abstract

The purification of stabilized oil/water emulsions is essential to meet the ever increasing demand for monitoring water in the environment, which has been addressed with superwetting carbon-based separation membranes. These include superhydrophilic carbon-based membranes whose progress in recent years and perspectives are reviewed in this paper. The membrane construction strategy is organized into four parts, vacuum-assisted self-assembly, sol–gel process, electrospinning, and vacuum-assisted filtration. In each section, the design strategies and their responding disadvantages have been comprehensively discussed. The challenges and prospects concerning the superhydrophilic carbon-based separation membranes for oily wastewater purification are also summarized to arouse researchers to carry out more studies.

Membranes for Oil/Water Separation: A Review

“…[15] Wei et al [16] reviewed the recent advances of oil/ water separation membranes special wettability. Further review by Gu et al [17] focused on superwetting separation membranes based on carbon and 2D laminar membranes for the application of selective ion and water transport. [18] The surface properties such as wetting are measured with contact angle, which influences hierarchical membrane structure.…”

Silica sulfuric acid coated on SnFe2O4MNPs: synthesis, characterization and catalytic applications in the synthesis of polyhydroquinolines

“…[22][23][24] Regarding the catalytic support materials, these spinel ferrite compounds have great potential in industry and technology as green heterogeneous catalysts in various organic functional group transformations and as catalytic supports. [25][26][27][28][29][30] Based on our interest in developing heterogeneous catalysts with the use of nanomaterials, we have recently reported the synthesis of novel heterogeneous catalytic supports that were functionalized by organic and inorganic ligands and complexes. 1,12,20,31,32 In the continuation of our studies, we wish to report the spinel normal SnFe 2 O 4 as a versatile nanomagnetic catalytic support, for the synthesis of a novel supported silica sulfuric acid catalyst, which is the rst report on the utilization of SnFe 2 O 4 MNPs as the catalytic support.…”

Dysprosium Incorporated Into Balsalazide Trapped Between the Functionalized Halloysite and g-C3N4 as an Efficient and Heterogeneous Catalyst for the Synthesis of Chromene Derivatives

“…2D-layered Graphitic carbon nitride (g-C 3 N 4 ) with s-triazine core has been considered as one of the most important class of materials with unique physicochemical properties and attracted the attention of a wide variety of researchers [25][26][27][28][29]. Regarding the carbon-based materials, these polymeric compounds have great potential in industry and technology as metal-free green heterogeneous catalysts in various organic transformations [30][31][32][33][34][35].…”
