Mechanochemical synthesis of functionalized silicon nanoparticles with terminal chlorine groups

  title={Mechanochemical synthesis of functionalized silicon nanoparticles with terminal chlorine groups},
  author={Steffen Hallmann},
A facile and efficient, one step method using high-energy ball milling (HEBM) to produce chloroalkyl-functionalized silicon nanoparticles is described. HEBM causes silicon wafers to fracture and exposes reactive silicon surfaces. Nanometer-sized, functionalized particles with alkyl-linked chloro groups are synthesized by milling the silicon precursor in presence of an x-chloroalkyne in either hexene or hexyne. This process allows tuning of the concentration of the exposed, alkyl-linked chloro… CONTINUE READING
