Ecofriendly Sunlight‐Mediated Nontoxic Bimetallic Nanoparticles: Synthesis, Reusable Catalytic Membrane, and Biosensor Applications

open access: yesAdvanced Science, EarlyView.
A novel sunlight‐driven synthesis produces Ag–Cu bimetallic nanoparticles (NPs) in just 10 min using nontoxic surfactants. These high‐quality NPs show excellent catalytic activity, functioning as reusable polytetrafluoroethylene (PTFE) and activated carbon fiber (ACF) supported catalysts for efficient conversion of p‐nitrophenol to p‐aminophenol, and ...

Ecofriendly Upcycling of Poly(vinyl chloride) Waste Plastics into Precious Metal Adsorbents

open access: yesAdvanced Science, EarlyView.
Poly(vinyl chloride) waste plastics are simply transformed into high‐performance precious metal (PM) adsorbents via a facile and green hydrazine‐functionalization process. The resultant adsorbent effectively and selectively recovers PM from real‐world leachates via its combined chemisorption and reduction mechanisms.
