Advanced Materials Interfaces, Journal Year: 2022, Volume and Issue: 9(27)

Published: Aug. 25, 2022

Recent advancements in separation and membrane technologies have shown a great potential removing oil from wastewaters effectively. In addition, the capabilities improved to fabricate membranes with tunable properties terms of their wettability, permeability, antifouling, mechanical that govern treatment oily wastewaters. Herein, authors critically reviewed literature on technology for oil/water specific focus on: 1) characterization, 2) development various materials (e.g., organic, inorganic, hybrid membranes, innovative materials), 3) design mixed matrix nanocomposite multilayers), 4) fabrication techniques surface modification techniques. The current challenges future research directions applications are also highlighted. Thus, this review provides helpful guidance toward finding more effective, practical, scalable solutions tackle environmental pollution by oils.

Published: March 17, 2023

Abstract Multifunctional separation membrane is usually realized by multi‐component collaborative construction, which makes the preparation method complicated and uncontrollable. Herein, a novel multifunctional photocatalytic prepared vacuum self‐assembly of single seaweed‐like g‐C 3 N 4 photocatalyst. The gives certain roughness, large specific surface area, excellent hydrophilicity abundant transport channels. Through systematic study, exhibits five oil‐in‐water emulsions with maximum flux 3114.0 ± 113.0 L m −2 h −1 bar for 1, 2‐dichloroethane‐in‐water (Dc/W) emulsion efficiency 97.4 0.1% chloroform‐in‐water (C/W) emulsion. In addition, area narrow bandgap render visible light absorption characteristics accelerate e − ‐h + pairs rate, giving degradation antibacterial properties. shows good eight different pollutants, among effect rhodamine B (RhB), methylene blue (MB), crystal violet (CV) were ≈100%. against E. coli S. aureus also close to 100%.

A Lotus‐Petiole‐Inspired Hierarchical Design with Hydrophilic/Hydrophobic Management for Enhanced Solar Water Purification

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(31)

Published: April 21, 2023

Abstract Solar‐driven vapor generation offers an affordable and sustainable approach to solve global freshwater scarcity. Creating interfacial solar evaporators capable of increasing water production rates matching human requirements is highly desirable but challenging due the slow transportation dynamics unavoidable oil‐fouling. Herein, a bio‐inspired lotus‐petiole‐mimetic microstructured graphene/poly(N‐acryloyl glycinamide) evaporator with integrated hydrophilic hydrophobic microregions developed. Through accurate control supramolecular interactions, optimized incorporating unique structural features wettability shows high light harvesting, enhanced activation, reduced energy demand for vaporization, enabling groundbreaking comprehensive performance along evaporation rate up 3.4 kg m −2 h −1 conversion efficiency ≈93% under one sun irradiation (1 kW ). Molecular simulations reveal that abundant hydrogen bonding sites polymeric networks can thermodynamically modulate escape behavior molecules. Notably, neither decrease in nor fouling on observed during prolonged purification process toward nano/submicrometer emulsions, oily brines, actual seawater, domestic wastewater. This study provides distinctive insights into behaviors at molecular level pioneers rational strategy design high‐yield freshwater‐generation systems wastewater containing complex contaminants.
