Hydrazide–pillar[5]arene-mediated silver nanoparticles for highly efficient reductive degradation of organic dyes

A new supramolecular approach toward the reductive degradation of organic dyes by hybridizing hydrophilic hydrazide-pillar[5]arene (HP5A) as surface-modifiers with silver nanoparticles (AgNPs) has been demonstrated. The fabricated supramolecular hybrid nanomaterial (denoted as HP5A-AgNPs) with ideal mono-dispersity, improved stability, and smaller size, show high catalytic activity in boosting organic dyes degradation, as delivered by a broad spectrum of organic dyes, including rhodamine B, rhodamine 6G, methylene blue, and methyl orange. This work expands the application scope of macrocycles-derived organic-inorganic nanohybrids into catalytic degradation and environmental protection areas.
