In this work the synthesis of a ZnAl2O4 spinel to be used as a support of metals and its characterization were studied. The methods used for the ZnAl2O4 preparation were: ceramic method (CM), mechanochemical synthesis in humid medium (HMS) and coprecipitation (COPR). ZnAl2O4 CM and ZnAl2O4 HMS showed negligible acidity, but the ZnAl2O4 COPR displayed a low acidity. The spinels obtained by COPR and...
