High Energy Ball‐Milling Synthesis of Nanostructured Ag

 · Nanostructured composites based on plasmonic Ag metal nanoclusters with monoclinc-BiVO 4 nanoparticles were prepared by high energy ball milling technique. The agglomerated morphology with a spherical shape of 50–100 nm sized BiVO 4 particles associated with homogeneous distribution of 5–10 nm Ag clusters significantly enhanced the photocatalytic activity for the degradation of acid blue dyes.

 · High- energy ball milling was carried out at room temperature using VQ-N Desktop high speed vibrating ball mill (Figure 1). One end of the principal axis of the mill connects with an eccentric wheel which is connected with the foundation of the ball mill through a tensile spring. When in operation the eccentric wheel swings at a high speed due to the tension of the spring. With the powerful vibration generated by the high speed swinging of the eccentric wheel the ball milling jars fixed on the eccentric wheel rotate and vibrate at 1200 rpm. A zirconium oxide jar (Figure 2) was used with a stainless steel vacuum cover during the milling process in vacuum environment. Granularity of the material specimens placed in the jar was less than 1mm and the maximum material loading was two thirds of the cubage of the ball milling
