Oxidizing agent impacting on growth of ZnO tetrapod nanostructures and its characterization

In this paper, the fabrication of ZnO tetrapod was investigated. It synthesized by thermal oxidation technique using metal zinc powder mixed with oxidizing agents such as hydrogen peroxide (H2O2) and ammonium persulfate ((NH4)2S2O8). The furnace heating temperature reached at 1000 °C in air. average diameter length a leg for mixture H2O2 from SEM were 45.3 nm 1.57 μm, respectively. oxygen vacancy (36%) higher than 33% only Zn. Growth mechanism processed via formation Zn nucleus growing wurtzite structure. directions crystal conformed [0001] direction. showed up high resolution TEM image lattice spacing 0.252 nm. From these results, work indicated that solution better reaction helper to make nanostructures anything else.
