Absract/Резюме: Gel matrix of the natural polymer starch has been employed as template for the preparation of ZnO nanocrystals via solution-solid technique. The template offers selective binding sites for Zn(II) under aqueous conditions. Controlled solvent-exchange, further isolation of solid product by microfiltration and drying, and subsequent removal of the template backbone enable the synthesis of spatially separated ZnO nanocrystals. The crystalline character and near narrow particle sizefatcat:3vbzj3675jae7ggvp5akwahwrm
