Synthesis of Zn(OH)2nanoparticles using electrochemical method

摘要

Zn(OH)2 nanoparticles have been synthesized by electrochemical method. Zinc metals were used as anode and cathode. The effects of potential, concentration and time of the electrolysis on the nanoparticles obtained were observed and characterized using XRD, PSA and UV-Vis spectrophotometer. The diffractogram shows that the nanoparticles obtained is in a good agreement with standard diffraction pattern of Zn(OH)₂nanoparticles, which identified as orthorhombic structure. The UV-Vis spectrum shows the highest intensity was achieved by electrolysis at 20 V in 0.04 M sodium citrate for 20 minutes which indicate the most Zn(OH)₂nanoparticle concentration formed in the solution. The peak was found at about 229 nm. The characterization using PSA shows that the Zn(OH)₂nanoparticles have a size distribution from 37 to 255 nm with the highest volume at 96.296 nm.
