•A facile, one-pot and solvent-less mechano-chemical approach.•A ‘green approach’ as it utilizes only biocompatible PVP and metal precursor.•Possible to produce nanoparticles in large scale and stored them for longer time.•No manipulative skills are needed to separate the particles in solid state.
Palladium nanoparticles are synthesized by an one-step, solvent-less, mechano-chemical reduction of potassium tetrachloropalladate(II) using an amphiphilic organic polymer, poly(vinylpyrrolidone). We demonstrate that poly(vinylpyrrolidone) can act both as reducing as well as capping agent in the solid state, without a solvent, for the synthesis of palladium nanoparticles at room temperature in conjunction with vibration milling. Besides, as an example, the application of the dendritic-like palladium nanoparticles as a catalyst is also investigated for the reduction reaction of 4-nitrophenol to 4-aminophenol at room temperature.
