摘要

A new discharge configuration for nanoparticle synthesis has been investigated in this work: microsecond discharge of liquid with aluminium pellets in the interelectrode gap. This plasma-based method enables efficient synthesis of high-yield aluminium hydroxide nanoparticles. We investigated nanoparticle synthesis using two conductivity liquid: distilled water (1 µS/cm) and (ii) and NaCl solution (1 mS/cm). The nanoparticle maximum production rate of our technique was ∼12 g/h. We used transmission electron microscopy and X-ray diffraction analysis to characterize the synthesized material. The linear size of the nanoparticles ranged from a few units to 600 nm, and the main crystalline phases of aluminium hydroxide were byerite and gibbsite.
