Zinc Oxide Nanopowder

Nanometer-sized zinc oxide powders were prepared with a “solution-combustion method (SCM).” This method used zinc oxide nanopowder as a semiconductor oxide catalyst to initiate light-induced redox reactivity in the presence of 150 ppm aqueous lead-ethylenediaminetetraacetic acid solution (Pb-EDTA) for photocatalysis under UV illumination. Removal rates of lead ions in the aqueous Pb-EDTA solution using SCM ZnO powder were compared with those of two other titanium dioxide photocatalysts, P-25 TiO2-powder (Degussa) and rutile TiO2 powder, prepared via a homogeneous precipitation process at low temperature (HPPLT). Using SCM ZnO nanopowder, complete removal of lead ions from the aqueous Pb-EDTA solution was observed within 25 min after UV irradiation. However, HPPLT TiO2 powder and P25 TiO2 powder took almost 45 and 65 minutes to completely remove the lead ions, respectively. Thus, lead ions removal efficiency of SCM ZnO nanopowder is at least twice higher than the efficiency of the other two titanium dioxide photocatalysts investigated.

Tribological properties of a composite mixture based on zinc oxide nanoparticles and nanolamellar tungsten and molybdenum disulfide powders have been studied. XRD and TEM of ZnO nanoparticles produced by electric discharge of metallic granules in an H2O2 solution were analyzed. The tribological tests showed ZnO nanoparticles additive in metal disulfide powders did not practically change the friction coefficient in comparison with pure WS2 and MoS2 powders at 25 °C in air. At 400 °C zinc oxide nanoparticles in composite lubricants positively affect the wear resistance.
