Summary: Graphene oxide (GO) composite membranes have been widely used in membrane modification due to their excellent properties, such as huge specific surface area, good electrical conductivity, good hydrophilicity, and various functional groups. The addition of GO in membranes has been proven to improve water permeability, molecular selectivity, membrane fouling mitigation, and contaminants decomposition. Recently, the development of laminated GO in membranes has achieved both high selectivity and high water permeability, overcoming the limitations of conventional polymeric or inorganic membranes. This review systematically summarizes the applications of GO composite membranes in three highlighted areas of environmental fields: desalination, gas separation, and wastewater treatment, and discusses the challenges faced with GO composite membranes.

Summary: The development of a cost-effective advanced membrane process for ethanol recovery and concentration is necessary due to the limitations of conventional methods. A gas stripping-assisted vapour permeation (GSVP) process using hydrophilic graphene oxide (GO) membranes was applied to selectively remove water and concentrate ethanol. The modified GSVP process showed lower energy consumption and achieved higher ethanol concentration compared to traditional distillation and vapour stripping processes.

Summary: An efficient chiral separation membrane was fabricated using bovine serum albumin (BSA) modified graphene oxide (GO) through EDC/NHS coupling chemistry. The BSA modified membrane successfully separated Phe racemate, achieving up to 96.1% excess enantiomer (ee) in the osmotic solution under optimal conditions. The addition of BSA not only increased the spacing in the membrane, but also created chiral channels for selective transport of L-Phe, resulting in high flux and selectivity. The microstructure of BSA was found to be crucial for the chiral separation performance of the membrane, as unfolding of its helical and globular three-dimensional structures weakened or eliminated the separation performance. Molecular docking simulation experiments supported this conclusion.

Summary: Subnanometer interlayer space in graphene oxide (GO) laminates is important for permselective membrane nanochannels. The precise control of nanochannel space and the role of confined nanochannel chemistry in selective water/ion separation are still challenging. This study used macrocyclic molecules with consistent basal plane but varying side groups to modify nanochannels in GO laminates, and demonstrated the side-group dependence of angstrom-precision tunability for channel free space and the energy barrier setting for ion transport. The study provides insights into functional-group-dependent intercalation modifications of GO laminates for structural control and nanochannel design.

Summary: Recent studies have found that graphene oxide (GO) has great potential as advanced separation membranes for water-related environmental applications. However, GO membranes often have low water permeability and stability issues. This study developed a novel approach involving intra-defect construction and cation cross-linking to prepare highly permeable and stable GO membranes for water purification. The membrane showed excellent water flux and selectivity, as well as long-term stability and pressure-resistance.

Summary: Graphene oxide (GO) membranes can be used for water treatment to remove organic molecules. However, the effect of pH on GO's properties leads to poor removal of positively charged model compounds. In this study, pH-responsive polymers were used to modify GO membranes, resulting in improved removal performance, water permeance, and long-term stability.

The membrane exhibited a polymer-dominated structure with ultra-high grafting amount of poly(sulfobetaine methacrylate) brushes. Due to the high hydration ability and water affinity of the polyzwitterion brushes, as well as the densified membrane structure, the membrane achieved excellent water/ethanol separation performance.

Summary: Molecular sieving membranes with ultra-selectivity for CO2/CH4 separation were successfully prepared using a template modulated crystal transition approach. Through one-minute overheating, organic template molecules were converted into tight carbon species and easily burned out by subsequent thermal treatment. The resulting membranes exhibited high CO2/CH4 selectivity and CO2 permeance. This strategy could pave the way for practical applications of all-silica zeolite membranes.

Summary: Stirred membrane reactors can recycle catalysts and separate products, but membrane fouling is a major limitation. This study investigated the dynamic process and mechanism of constant pressure filtration membrane fouling through experiments and computational fluid dynamics (CFD) simulation. The results showed that the filtration model at high shear position followed the cake filtration model according to the Hermia model, while the filtration model at low shear position followed the combined filtration model due to different particle accumulation speeds. It was found that higher shear rates or lower trans-membrane pressure resulted in easier stabilization of the filtration system. The smaller the porosity epsilon, the larger the fraction of small particles in the filter cake. Finally, the study explained the mechanism of membrane fouling based on changes in particle radial velocity and acceleration at the micro level.
