摘要
ZrO2 carriers with different crystal structure including monoclinic phase (m-ZrO2), tetragonal phase (t-ZrO2) and amorphous phase (a-ZrO2) were prepared. Subsequently, Cu/m-ZrO2, Cu/t-ZrO2, and Cu/a-ZrO2 catalysts were prepared by sedimentation method and then were applied to synthesize iminodiacetic acid by the dehydrogenation of diethanolamine. The structures of the catalysts were characterized by XRD, nitrogen-physical adsorption desorption, XPS, H2-TPR and CO2-TPD. The results showed that Cu/m-ZrO2 catalyst's interface was more conducive to the stable existence of Cu+/Cu0, with more alkaline sites and better oxidation resistance. In the dehydrogenation of diethanolamine, Cu/m-ZrO2 catalyst had better performance, the reaction time was 2.5 h, and the yield of iminodiacetic acid was 97.64%. © 2019, Editorial Office of FINE CHEMICALS.
