Selective Capture and Continuous Recovery of Sulfur-Containing Molecules from Flowing Wastewater Using a Capillary Ag2Mo3O10·1.8H2O/Carbon Fiber Membrane System

This work presents a novel, membrane-inspired hybrid framework composed of Ag₂Mo₃O₁₀·1.8H₂O nanowires grown in situ on carbon fiber cloth (CFC) for the continuous and selective recovery of high-value sulfur-containing molecules from organic wastewater. The framework forms an integrated hierarchical porous network rich in micro-/nano-channels, which facilitates efficient, capillary-driven water transport. Owing to its mesoporous texture and specific Ag-S coordination affinity, the material shows exceptional selectivity toward sulfur-containing dyes, enabling rapid adsorption (>94% removal of methylene blue within 10 min) and high specificity in mixed solutions. The hybrid also exhibits excellent reusability, maintaining high recovery efficiency over repeated adsorption-desorption cycles. When configured into a continuous-flow system, the framework operates without external pressure and achieves a water transport rate of 1875 mL·h^-1·m^-2. These findings underscore the potential of the Ag₂Mo₃O₁₀·1.8H₂O/CFC hybrid as an efficient, scalable, and sustainable platform for resource-oriented wastewater treatment.
