A new method of electroless plating–calcination was developed to prepare Cu/Al2O3 with high catalytic activity and long operational life for catalytic ozonation. First, the effects of key preparation parameters on the catalytic activity of new Cu/Al2O3 were investigated. In addition, new Cu/Al2O3 prepared by electroless plating–calcination and conventional Cu/Al2O3 prepared by impregnation–calcination were characterized. The results show that when Cu/Al2O3 were prepared by electroless plating–calcination, copper oxides were uniformly and densely deposited on the surface of Al2O3, and the copper compounds consist of CuO. Furthermore, the catalytic activity and operational life of the two kinds of Cu/Al2O3 were also investigated comparatively. The results confirmed the advantage of the new method for the preparation of Cu/Al2O3 for catalytic ozonation. Finally, the degradation pathway was proposed. It can be concluded that electroless plating–calcination is a promising technology to prepare the robust Cu/Al2O3 with high catalytic activity for the decomposition of ozone.

化学镀-煅烧工艺增强Cu / Al 2 O 3臭氧化的催化活性
开发了一种新的化学镀－煅烧方法，以制备具有高催化活性和长寿命的Cu / Al 2 O 3进行催化臭氧化反应。首先，研究了关键制备参数对新型Cu / Al 2 O 3催化活性的影响。另外，对通过化学镀-煅烧制备的新Cu / Al 2 O 3和通过浸渍-煅烧制备的常规Cu / Al 2 O 3进行了表征。结果表明，通过化学镀-煅烧制备Cu / Al 2 O 3时，氧化铜均匀而致密地沉积在Al表面2 O 3，并且铜化合物由CuO组成。此外，还对两种Cu / Al 2 O 3的催化活性和使用寿命进行了比较研究。结果证实了用于催化臭氧化的制备Cu / Al 2 O 3的新方法的优点。最后，提出了降解途径。可以得出结论，化学镀-煅烧是制备具有高催化活性的强固型Cu / Al 2 O 3的有前途的技术，可分解臭氧。
