Overcoming the permeability-selectivity challenge in water purification using two-dimensional cobalt-functionalized vermiculite membrane

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Jan. 9, 2024

Abstract Clean water and sanitation are major global challenges highlighted by the UN Sustainable Development Goals. Water treatment using energy-efficient membrane technologies is one of most promising solutions. Despite decades research, permeability-selectivity trade-off remains challenge for synthetic membranes. To overcome this challenge, here we develop a two-dimensional cobalt-functionalized vermiculite (Co@VMT), which innovatively combines properties filtration nanoconfinement catalysis. The Co@VMT demonstrates high permeance 122.4 L·m −2 ·h −1 ·bar , two orders magnitude higher than that VMT (1.1 ). Moreover, applied as nanofluidic advanced oxidation process platform to activate peroxymonosulfate (PMS) degradation several organic pollutants (dyes, pharmaceuticals, phenols) shows excellent performance (~100%) stability (for over 107 h) even in real-world matrices. Importantly, safe non-toxic effluent quality ensured membrane/PMS system without brine, totally different from molecular sieving-based with concentrated remaining brine. This work can serve generic design blueprint development diverse catalytic membranes persistent issue purification.

Tempospatially Confined Catalytic Membranes for Advanced Water Remediation

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(37)

Published: Feb. 12, 2024

Abstract The application of homogeneous catalysts in water remediation is limited by their excessive chemical and energy input, weak regenerability, potential leaching. Heterogeneous catalytic membranes (CMs) offer a new approach to facilitate efficient, selective, continuous pollutant degradation. Thus, integrating filtration with heterogeneous advanced oxidation processes (AOPs) can promote thermodynamic kinetic mass transfers spatially confined intrapores diffusion‐reaction processes. Despite the remarkable advantages CMs, engineering practically restricted due fuzzy design criteria for specific applications. Herein, recent advances CMs are critically reviewed flow tempospatially proposed. Further, state‐of‐the‐art CM materials mechanisms reviewed, after which tempospatial confinement comprising nanoconfinement effect, interface transfer emphasized, thus clarifying roles construction performance optimization CMs. Additionally, fabrication methods based on pore sizes summarized an overview evaluations presented. Finally, future directions research treatment,
