The synergistic treatment of oily wastewater containing organic hazards and emulsified oils remains a big challenge for membrane separation technology. Herein, the photocatalytic membrane, which combined physical barrier catalytic oxidation-driven degradation functionality, was fabricated via anchoring nanoflower-branched CoAl-LDH@PANI Z-scheme heterojunction onto porous polyacrylonitrile mat using tannic acid as an adhesive. assembly such offered superior performance soluble dyes tetracycline (up to 94.3%) with improved activity 2.33 times compared CoAl-LDH@pPAN membrane. Quenching experiments suggested that •O2– most reactive oxygen species in reaction system composite greatly enhanced attributed effective inhibition photogenerated hole–electron combination PANI carrier, charge transferring from LDH PANI. possible mechanism proposed based on VB-XPS, electron spin resonance spectroscopy, DRS technologies, confirmed by density functional theory calculation. Meanwhile, benefiting superhydrophilic/oleophobic feature low oil adhesion, exhibited high permeability isooctane emulsion (3990.39 L·m–2·h–1), structure stability, satisfactory cycling performance. This work provided strategy develop superwetting membranes treating complex multicomponent pollutants chemical industry.

Cr(VI)-Responsive Ink with Four-Dimensional Printing of an Ultracompact Hydrogel Optical Fiber Microsensor

ACS Sensors, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 7, 2025

Hydrogel is emerging as a promising material for smart sensors due to its remarkable stimuli-responsiveness and biocompatibility. However, traditional methods like ultraviolet curing or imprinting could not yield ultracompact hydrogel microstructures with sophisticated design controllable morphology, posing challenges in developing highly integrated microfluidic sensors. With the advanced femtosecond laser (Fs) direct writing technology, an intelligent optical microsensor prepared real-time monitoring of trace hexavalent chromium ions [Cr(VI)] water. First, Cr(VI)-responsive ink containing 3-acrylamidopropyl-trimethyammonium chloride (ACTC) developed, boasting printing resolution ∼250 nm. Subsequently, fiber-tip Fabry–Perot cavity (FPC) Cr(VI) printed using multimaterial TPP strategy. The sensor shows size (∼100 μm) high specificity detecting liquid samples. detection limit 1.48 × 10–9 M makes it suitable rapidly Cr(VI). on-chip MEMS provides platform environmental protection analytical science fields.
