Area of Science:

• Materials Science
• Environmental Science
• Nanotechnology

Background:

• Organic wastewater often contains high-value sulfur-containing molecules.
• Efficient and selective recovery methods are crucial for resource utilization and pollution control.
• Existing methods may lack selectivity, efficiency, or scalability.

Purpose of the Study:

• To develop a novel hybrid framework for continuous and selective recovery of sulfur-containing molecules from organic wastewater.
• To investigate the material's adsorption properties, water transport capabilities, and reusability.
• To evaluate the framework's potential for resource-oriented wastewater treatment.

Main Methods:

• In situ growth of Ag2Mo3O10·1.8H2O nanowires on carbon fiber cloth (CFC).
• Fabrication of a membrane-inspired hybrid framework with hierarchical porous structure.
• Testing of adsorption capacity, selectivity (e.g., methylene blue removal), and reusability.
• Evaluation of continuous-flow performance, including water transport rate.

Main Results:

• The Ag2Mo3O10·1.8H2O/CFC framework exhibited efficient and selective adsorption of sulfur-containing dyes (>94% methylene blue removal in 10 min).
• The material demonstrated rapid capillary-driven water transport (1875 mL·h-1·m-2) without external pressure.
• High reusability was observed over multiple adsorption-desorption cycles.
• The hybrid framework showed high specificity even in mixed solutions.

Conclusions:

• The Ag2Mo3O10·1.8H2O/CFC hybrid framework is a promising material for selective sulfur-containing molecule recovery.
• The integrated hierarchical porous network facilitates efficient water transport and adsorption.
• This scalable and sustainable platform holds potential for resource-oriented wastewater treatment applications.
