Superhydrophilic Photothermal-Responsive CuO@MXene Nanofibrous Membrane with Inherent Biofouling Resistance for Treating Complex Oily Wastewater

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(15), P. 19537 - 19550

Published: April 2, 2024

MXene, a recently emerged 2D material, has garnered substantial attention for myriad of applications. Despite the growing interest, there remains noticeable gap in exploring MXene-based membranes simultaneous achievement photomodulated oil/water separation, bacterial resistance, and removal pollutants treatment oily wastewater. In this work, we have successfully synthesized novel multifunctional CuO@MXene-PAN nanofibrous membrane (NFM) featuring unique nanograin-like structures. Benefitting from these structures, resultant shows excellent superwetting properties, significantly enhancing its performance separation. addition, membrane's photothermal property boosts permeance by 40% under visible light illumination within 30 min. Furthermore, decent dye efficiency an aqueous solution, e.g., Rhodamine B (RhB), promoting efficient degradation with high reusability light. Most remarkably, exhibits superior anti-biofouling capability consistently resists adhesion microorganisms such as cyanobacteria over 14 day period. Thus, combined effect responsivity, photocatalytic activity, antibacterial NFM contributes to intricate This synergistic combination properties could be appealing strategy broad development materials prevent fouling during actual separation performance.

Published: April 26, 2024

Abstract The conventional membranes used for separating oil/water emulsions are typically limited by the properties of membrane materials and impact fouling, making continuous long‐term usage unachievable. In this study, a filtering electrode with synchronous self‐cleaning functionality is devised, exhibiting notable antifouling ability an extended operational lifespan, suitable separation emulsions. Compared original Ti foam, in situ growth NiTi‐LDH (Layered double hydroxide) nano‐flowers endows modified foam (NiTi‐LDH/TF) exceptional superhydrophilicity underwater superoleophobicity. Driven gravity, rejection rate over 99% achieved various containing oil content ranging from 1% to 50%, as well oil/seawater flux recovery exceeds 90% after one hundred cycles 4‐h filtration period. enhanced performance realized through “gas bridge” effect during aeration electrochemical anodic oxidation. internal within pores contributes removal foulants. This study underscores potential coupling metal technology, providing paradigm exploration novel membranes.
