Zinc oxide particles were synthesized by precipitation from an aqueous solution of zinc nitrate tetrahydrate, R-(+)-cysteine and hexamethylenetetramine (HMTA, urotropine). Hollow microspheres of ZnO-cysteine hybrid material with a diameter of ca. 1 mu m and a wall thickness ca. 50 nm were obtained. After heating up to 850 degrees C pure ZnO microspheres of roughly the same size were formed. The particles were characterized by XRD, SEM, FT-IR and TGA. (c) 2007 Elsevier Ltd. All rights reserved.
