A series of stable and well‐dispersed random alloy nanoparticles of palladium and gold was synthesized by a template method using dendrimers. The synthesized nanoparticles were qualitatively and quantitatively characterized by UV‐Vis spectrophotometry (UV‐Vis), High‐resolution transmission electron spectroscopy (HR‐TEM), energy dispersed X‐ray spectroscopy (EDS) and inductively coupled plasma optical emission spectrometry (ICP‐OES). Metal nanoparticles size (Pd55Au55/Dens‐OH ((2.21 ± 0.41) nm)) were significantly close to the calculated nanoparticles size (Pd55Au55/Dens‐OH (2.59 nm)). Catalytic reduction of methyl orange was performed as a model reaction in the presence of sodium borohydride. The kinetic investigation was monitored through a microplate reader. The obtained data were kinetically interpreted according to the Langmuir‐Hinshelwood approach. The catalytic process described an exothermic process, where the model compound physicochemical adsorption on the nanoparticles active surface site was found to be a non‐spontaneous process.
