Synthesis and characterization of zinc oxide tetrapods from zinc galvanization dross

摘要

As an interesting material in large field area, ZnO synthesize has been widely observed. In this research, synthesize was carried out using zinc dross, waste from galvanization process, as starting material by simple heat treatment method. The as-synthesized ZnO obtained were further underwent post-anneal and post-hydrothermal treatment series. From the characterization data, it was found that highest crystallite size was obtained in sample treated with post-hydrothermal treatment at 150°C for 12 hours with value of 1371 nm, which corresponds to its lowest Eg value of 3,086 eV.
