TiVCT_X MXene/Graphene Nanosheet-Based Aerogels for Removal of Organic Contaminants from Wastewater

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(7), P. 7312 - 7326

Published: March 25, 2024

Efficient removal of broad-spectrum organic pollutants is crucial in wastewater treatment. This research focuses on the synthesis three-dimensional TiVCTX MXene/graphene nanosheet-based aerogels, known as TiVCTX/GAs, using a straightforward hydrothermal self-assembly method, followed by freeze-drying. The integration bimetallic MXene and graphene aerogel TiVCTX/GAs results an impressive capability for multiple contaminants from wastewater. exhibit effective adsorption various dyes drugs, with capacities reaching 319.67, 303.45, 229.97, 217.87, 283.38 mg·g–1 methylene blue, rhodamine B, Congo red, methyl orange, tetracycline hydrochloride, respectively.

Engraving Polyamide Layers by In Situ Self-Etchable CaCO₃ Nanoparticles Enhances Separation Properties and Antifouling Performance of Reverse Osmosis Membranes

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(14), P. 6435 - 6443

Published: March 29, 2024

Nanovoids within a polyamide layer play an important role in the separation performance of thin-film composite (TFC) reverse osmosis (RO) membranes. To form more extensive nanovoids for enhanced performance, one commonly used method is to incorporate sacrificial nanofillers during exothermic interfacial polymerization (IP) reaction, followed by some post-etching processes. However, these post-treatments could harm membrane integrity, thereby leading reduced selectivity. In this study, we applied situ self-etchable taking advantage strong acid and heat generated IP. CaCO3 nanoparticles (nCaCO3) were as model nanofillers, which can be etched reacting with H+ leave void nanostructures behind. This reaction further degas CO2 nanobubbles assisted IP layer. These facilitate water transport enlarging effective surface filtration area reducing hydraulic resistance significantly enhance permeance. The correlations between nanovoid properties systematically analyzed. We demonstrate that nCaCO3-tailored improve antifouling propensity rejections boron As(III) compared control. study investigated novel strategy applying gas precursors engrave provides new insights into design synthesis TFC
