Cu/Co₃O₄-ZrO₂ catalyst was synthesized by a simple co-precipitation method, and its self-oxidation behavior after reduction reduced the particle size of Co₃O₄. Cu/Co₃O₄-ZrO₂ demonstrated a high performance during the dehydrogenation of diethanolamine, reaching a 96% yield of iminodiacetic in 30 min. The catalyst was characterized by XRD, XPS, TEM, SEM, and H₂-TPR. The results showed that strong Cu-oxide interactions, the co-catalysis of biactive components, and the higher number of oxygen vacancies of Cu/Co₃O₄-ZrO₂ were responsible for the enhanced catalytic activity during diethanolamine dehydrogenation. Co₃O₄ particles improved the dispersion and stability of Cu NPs and inhibited the sintering of loaded Cu NPs.

通过简单的共沉淀法合成了Cu / Co ₃ O ₄ -ZrO ₂催化剂，还原后的自氧化行为降低了Co ₃ O ₄的粒径。Cu / Co ₃ O ₄ -ZrO ₂在二乙醇胺脱氢过程中表现出很高的性能，在30分钟内达到亚氨基二乙酸96％的收率。通过XRD，XPS，TEM，SEM和H ₂ -TPR表征该催化剂。结果表明，Cu / Co ₃ O ₄ -ZrO ₂具有较强的Cu-氧化物相互作用，双活性组分的共催化作用和较高的氧空位数量。是造成二乙醇胺脱氢过程中催化活性增强的原因。Co ₃ O ₄颗粒改善了铜纳米颗粒的分散性和稳定性，并抑制了负载铜纳米颗粒的烧结。
