摘要: Abstract High-density and well-dispersed Ag nanoparticles (Ag NPs) with a mean size of 20 nm have been successfully supported on the surface polyacrylamide functionalized polypyrrole/graphene oxide (PAM/PPy/GO) nanosheets. The obtained Ag/PAM/PPy/GO composite nanosheets exhibited an excellent catalytic activity for reduction 4-nitrophenol by NaBH4 kinetic reaction rate constant 3.38 × 10−2 s−1 due to synergistic effect all components corresponding mechanism has revealed investigating different performance: GO two-dimensional structures offered large area immobilization more NPs; PPy high electric conductivity promoted electron transport in 4-NP; PAM did not only act as good linker between NPs PPy/GO synthesis nanosheets, but also could facilitate efficient contact 4-NP were active site 4-NP, respectively.
