Abstract This work reports the results of spectrophotometric, dynamic light scattering (DLS) and microscopic (SEM) studies of the gold nanoparticles (AuNPs) deposition on activated carbon (AC) surface modified with primary (ethanolamine) and secondary (diethylenetriamine and triethylenetetramine) amines. It was found that this method is efficient for deposition of AuNPs from aqueous solution. However, nanoparticles change their morphology depending on the kind of amine used in experiments. On the AC surface modified with ethanolamine, the uniform spherical AuNPs were formed. In case of diethylenetriamine and triethylenetetramine application, the agglomerates of AuNPs are present. The diameter of individual AuNPs did not exceed 15 nm and was bigger as compared with the diameter of particles present in precursor solution (ca. 10 nm).

: In this paper, activation procedures under size effects of some gold nanoparticles (Au101, Aunaked and Aucitrate) and nanoclusters (Au8 and Au9) immobilized on powder Norit® activated carbon (abbreviated to AC) and/or Vulcan carbon (abbreviated to VC) on the catalytic activity of gold nanocatalysts were studied. The gold nanostructures were activated through the washing procedure with a base in MilliQ water or hot toluene and then followed by heating in static air (abbreviated to W+S) or under vacuum (abbreviated to W+V) at 100 °C for 3 h. The highest activity of gold nanocatalysts for benzyl alcohol oxidation was obtained for activated (W+V) ‘naked’ gold nanoparticles immobilized on Norit® activated carbon when the gold nanoparticle diameters was ~4.4 nm.
