2) Thermally stable up to 300 °C
3) Excellent cycling stability with minimal capacity loss over 500 water adsorption–desorption cycles
Preservation
1) Keep in dry and cool condition
2) Activate at 80 °C under vacuum for 24 h or 150 °C under vacuum for 3 h before use
Other Features
Anionic framework; reversible cation exchange (Li⁺, Na⁺, K⁺, Mg²⁺, TMA⁺); visible-light responsive (band gap 2.73 eV); adsorbs SO₂ and CO₂; high-capacity water uptake at 4.3–11.1% RH with negligible hysteresis; regenerable with NaCl solution
Applications
1) Efficiently adsorbs cationic pharmaceutical pollutants from wastewater
2) Photocatalytic degradation of antibiotics (sulfamethazine) under visible light
3) Selective adsorption of CO₂, SO₂ for gas separation
4) Atmospheric water harvesting, desiccation and adsorption heat pumps
