Hydrazone-linked COFs with N/O synergistic sites achieving ultrahigh and fast Pd(II) capture under acidic conditions

Key Points

• Palladium capture efficiency reached unprecedented levels under acidic conditions, indicating strong ligand interactions.
• Capture rates for Pd(II) were measured at notably high speeds, enhancing potential applications in recovery processes.
• The development of hydrazone-linked covalent organic frameworks enables improved capture through synergistic site design.
• Implications for environmentally friendly palladium recovery highlight the application of this technology in sustainable practices.
