Summary
Vanadium carbide (V2C) MXene-modified ceramic membranes show over 99% oil rejection for wastewater treatment. This advanced material offers robust oil-water separation and resistance to fouling, paving the way for sustainable solutions.
Area of Science:
- Materials Science
- Environmental Engineering
- Nanotechnology
Background:
- Efficient oil-water emulsion separation is crucial for sustainable wastewater treatment.
- Two-dimensional MXenes offer unique properties like hydrophilicity and stability for membrane applications.
- Vanadium carbide (V2C) MXene is an under-explored material with potential for surface modification.
Purpose of the Study:
- To develop and evaluate ceramic membranes surface-modified with V2C MXene for oil-in-water emulsion separation.
- To investigate the effect of V2C loading on membrane performance.
- To assess the fouling resistance and stability of the modified membranes.
Main Methods:
- Ceramic membranes were fabricated with varying V2C MXene loadings (2, 4, and 6 mg).
- Membrane performance was characterized by oil rejection, flux recovery ratio (FRR), and underwater-oil contact angle (UWOCA).
- Stability was tested across a range of pH values and oil concentrations.
Main Results:
- The membrane with 6 mg V2C loading achieved >99% oil rejection and >90% FRR.
- Optimized membranes exhibited underwater superoleophobicity (UWOCA = 153°), indicating excellent anti-fouling properties.
- Stable separation performance was observed across diverse pH and oil concentration conditions.
Conclusions:
- V2C MXene-modified ceramic membranes demonstrate high efficiency and robustness for oil-water separation.
- These membranes show significant potential for advanced wastewater treatment applications.
- Future research will explore machine learning for performance optimization and scale-up.

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

5.5K
Detergents are used to purify the integral proteins of the membrane. The hydrophobic portion of the detergent can replace membrane phospholipids while solubilizing the membrane proteins. When detergent monomers reach a specific concentration in a solution called critical micelle concentration (CMC), they form micelles. Above CMC, the concentration of the detergent monomers remains in equilibrium with the micelle. The number of detergent monomers present in the CMC varies for each detergent, and...

Solution, Solubility, and Solubility Equilibrium
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules,...

Micelle formation is an intricate process that hinges on the properties of amphiphilic or amphipathic molecules and the conditions of the system in which they are found. Amphiphilic molecules, which have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts, play a critical role in this process.In aqueous environments, these molecules arrange themselves such that their hydrophilic heads are turned towards the water phase, while their hydrophobic tails are oriented away...
