“…Research has also shown that graphitic carbon nitride (g-C 3 N 4 ) is capable of self-cleaning and separation due to its wettability. The stability and unique physicochemical characteristics of the g-C 3 N 4 in alkaline or acidic media have attracted much research interest as a new carbon nanomaterial. , The preparation of 2D g-C 3 N 4 nanosheets by the exfoliation process has increasingly enhanced its photocatalytic activity and wettability in oil–water separation. − Furthermore, g-C 3 N 4 can also be incorporated to provide a self-cleaning function to the membrane. , …”

“…SSM was coated with nanocomposites and TPU as a binder to study its separation performance. 31 All samples of the nanocomposite-coated mesh were investigated by WCA and underwater oil contact angle (UOCA) measurements (Figure 4a,b). The surface hydrophilicity increased with the addition of 5% Zn(OH) 2 , due to the increase in oxygen-containing functional groups and specific surface area.…”

It has been widely recognized that efficient approaches to water–oil separation need to be developed and designed. It is the objective of this study to improve and optimize the performance of g-C3N4 for oil–water separation by anchoring Zn(OH)2. Additionally, the as-prepared g-C3N4/Zn(OH)2 nanocomposites containing different amounts of Zn(OH)2 were investigated to determine the effect of two factors of porosity and surface defects in the water-removing of oil–water mixtures. The results show that oxygen-containing groups in this specific g-C3N4/Zn(OH)2 nanocomposite have a greater impact on wettability behavior and water-removing separation performance than porosity. Density functional theory (DFT) calculations demonstrated that the adsorption energy of water is larger than that of oil molecules on the g-C3N4/Zn(OH)2, confirming that the prepared coated mesh can be used as a potential material for water–oil separation. Moreover, the self-cleaning property of the nanocomposite-coated mesh was demonstrated by the removal of adsorbed oil in contact with the surface. In this study, it was also attempted to perform water and oil separation with good performance. Therefore, the perfluorooctanoic acid (PFOA) was also used to reduce energy in g-C3N4@Zn(OH)2@PFOA mesh, leading to super-hydrophilic/super-oleophobic wettability. Ultimately, a new mesh coated with g-C3N4@Zn(OH)2@PFOA nanocomposite was successfully separated oil-in-water emulsion with a high efficiency of 99.99%.

The field of plasma−liquid interactions is rapidly growing, with increasing publications across applications. While plasma's interactions with water and oil have been researched, there is a notable gap in the study of plasma−emulsion interactions and their practical applications. Investigating plasma−emulsion interactions offers a dual advantage, as demonstrated in this study, as it is applicable to both water/oil separation and emulsion stabilization processes. This study introduces a groundbreaking approach utilizing the fountain dielectric barrier discharge (FDBD) plasma reactor. The reactor exposes a model emulsion to different plasma gases, such as air, nitrogen, argon, and ammonia, along with varying parameters of plasma input voltage and treatment time. Consequently, due to demulsification, the emulsion segregates into distinct water and oil phases. Remarkably, the results demonstrate that short-term plasma treatment leads to the separation of over 99% of emulsified water. However, prolonged exposure to plasma for around 7 min reveals a decrease in the volume of freeseparated water, implying the occurrence of stable emulsion formation instead of further demulsification. To optimize experimental conditions for compliance with regulatory requirements, the study employs the response surface methodology (RSM). Adapting pH and separation contours in three-dimensional (3D) RSM plots shows that achieving higher separation is likely associated with higher pH levels in air, nitrogen, and argon plasmas. Notably, the plasma treatment involving ammonia gas elevates the pH level and yields the highest degree of separation compared with air, nitrogen, or argon plasmas.
