Abstract
For the reduction of 4-nitrophenol to 4-aminophenol, gold nanoparticles (AuNPs) below 10 nm have high catalytic activity. However, AuNPs in aqueous solution or organic solvents are not stable in the absence of stabilizers. Here, we describe polyion complex (PIC) micelles as the stabilizer to prepare highly dispersed AuNPs for the first time. The preparation route is very gentle, easy, and reproducible. PIC micelles-stabilized AuNPs are approximately 8 nm in size and exhibit high catalytic activity for the reduction of 4-nitrophenol. The kinetic reaction rate constant is 0.51 min−1 with a good linear relationship. On the basis of their excellent colloidal stability and catalytic activity, PIC micelles-stabilized AuNPs are greatly hoped for further applications in catalysis.
