During the combustion process only one phase, ZnO was obtained. The phase formation and structural transformation at every step of routes for the synthesis were followed by XRD and IR analysis. Our previous investigation in the same system, applying the hydrolytic sol-gel method showed that the type of precursor and the order of adding the components influenced on the microstructure of the final product in the ZnO-TiO2 system, which was proved also in this study. The obtained powders possess photocatalytical activity against organic dye (Malachite green) in the UV and Vis region.enArticle
