Green Synthesis of Silver Nanoparticles by Low-Energy Wet Bead Milling of Metal Spheres

摘要: A low-energy, magnetically-driven milling technique for the synthesis of silver nanoparticles is proposed, where grinding medium and metal precursor consisting spheres have same shape size, belonging to a millimetric scale. The process carried out at room temperature in aqueous solvent, different types capping agents been dissolved damp particle agglomeration. diameters, determined by dynamic light scattering transmission electron microscopy, compared with those typical conventional wet-chemical bottom-up processes. use initial size allows overcome some drawbacks limitations distinctive bead-milling equipment, generally requiring complex operations separation recovery media. bead/nanoparticle diameter ratio obtained this approach higher than that most previous wet bead techniques. method described here represents simple, one-pot, cost-effective, eco-friendly starting from bulky solid.
