Porous cobalt-doped alumina catalysts were synthetized using the sol-gel method. The synthesized materials were calcined at 500 °C, 1000 °C and 1100 °C and denoted as CoA-500, CoA-1000 and CoA-1100, respectively. Catalysts were characterized using XRPD, H2-TPR and low temperature N2 physisorption techniques. Applied techniques showed that the annealing temperature affects the structural and textural properties of the catalysts. The synthesized catalysts were investigated in the degradation of tartrazine in the presence of Oxone®. The influence of the mass of catalyst, reaction time, reaction temperature and initial pH were investigated. The temperature increase was beneficial for the dye degradation rate. CoA-500 was proved to be the most efficient among the investigated catalysts. The reaction followed the pseudo-first order kinetics for all investigated temperatures for all three catalysts. All cobalt-doped alumina catalysts were found to be efficient in the Oxone® induced catalytic ...degradation of tartrazine with CoA-500 showing the best performance.
