Abstract Optical properties, structure, size and morphology of colloidal gold nanoparticles (AuNPs) stabilized by a series of hydrophilic polymers possessing nonionic, anionic, cationic and amphoteric nature were characterized by visible spectroscopy, dynamic light scattering (DLS), X-ray diffraction (XRD) and scanning electron microscopy (SEM), transmission electron microscopy (TEM). The polymer-protected AuNPs were prepared by “one-pot” synthetic protocol. The kinetics of formation of AuNPs was determined. The influence of the molecular weight (Mw) of polymers and concentration of AuNPs on the size of AuNPs was shown. The catalytic activity of polymer-protected AuNPs with respect to hydrogenation of 4-nitrophenol was studied. High conversion degree of 4-nitrophenol to 4-aminophenol was evaluated by visible spectroscopy.
