In this experimental work, a nanostructured ZnO like nano flowers doped with different elements, X=Pd, Pt, Co, Mn, Ni are synthesized. X-ray diffraction (XRD), Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) are used for characterization of the materials. The materials were synthesized from pyrolysis of Zn(NO3)2 solution with triethanolamine with adequate dopant. After complete dehydration of the precursor solution, a black, carbonaceous, mesoporous fluffy mass is obtained, which after calcinations produces the desired nanocrystalline materials. Formation of hexagonal single phase ZnO nanoparticle is confirmed by the careful analysis of XRD data. It follows from non oriented growth for undoped nanostructure to strongly (002) oriented, at intermediate (~1at. %) doping level. The materials are also characterized through TEM, and energy dispersive X-ray (EDX) analysis to obtain the shape, size, morphology and elemental compositions.
