Rationally designed bifunctional covalent organic polymers for broad-spectrum-driven photothermal catalytic Cr(VI) reduction and iodine capture

Key Points

• Photothermal catalytic reduction effectively decreases Cr(VI) in aqueous solutions, showcasing strong degradation potential.
• The bifunctional polymers achieved a reduction rate of 90% for Cr(VI) within 60 minutes in controlled tests.
• Assessment using synthesized covalent organic polymers highlights their dual function in contaminant capture.
• Promising results support further development for environmental applications, suggesting broad-spectrum remediation needs.
