Preparation of zinc oxide nano- and micro-structures using hydrothermal-template method and their applications

Pure zinc oxide (ZnO) was successfully synthesized using various non bio- and biotemplates namely, sodium dodecyl sulfate (SDS), cetyl trimethylammonium bromide (CTAB), palm olein (PO), uncooked- and cooked rice. ZnO nano- and microstructures were synthesized through hydrothermal method. The physico...
