dc.description.abstractIt is well known that the citric acid is used as a chelating agent which forms poly (basic acid) chelates with the metal cations in a nano-powder synthesis route. The aim of this investigation is to study the influence of the citric acid on the crystallization process in obtaining ZnO/TiO2 nano-composites. Samples have been synthesized by the aqueous sol-gel method applying two different schemes with and without citric acid, respectively. Several compositions containing different TiO2 (10, 90 mol %) and ZnO (10, 90 mol %) amounts were investigated. The as-prepared powders were calcinated from 100 to 500°C. The phase formation and structural transformation at every step of the synthesis route were followed by X-ray phase analysis and IR spectroscopy and the obtained results were compared.
