Fabrication of Au-polymer hybrid colloids via a pH-modulated in situ reduction process for improved catalytic activity

Abstract Here, we reported a novel strategy for the controllable synthesis of Au nanoparticles within functional microgels. By simply mixing Au(Cl) 4 - ions with microgel dispersion at room temperature several hours, Au(III) were reduced into Au(0) on surface Without use any additional reductant, reduction was realized and controlled by tuning volume base solution as result unique reductive 3-carbonyl- N -vinylcaprolactam structure inside Moreover, hybrid microgels showed efficient catalytic activities model reaction 4-nitrophenol (Nip). These results revealed that fabricating Au-polymer hybrids possesses great potential in field wastewater treatment.
