TD-DTA and XRD was carried out to investigate the effect of Ce on the stability of the substrate and the activated substance, CuO at high temperature. The results showed that the doping of Ce restrained effectively the phase change of substrate from γ-Al2O3 to α-Al2O3 and the formation of CuAl2O4 , which was produced by the reaction between CuO and Al2O3 during the process of wet air oxidation. The degradation experiment of phenol wastewater showed the doping of Ce can improve the activity of catalyst well. The catalyst with Cu∶Ce∶γ-Al2O3=6∶6∶100 (mass percentage) has the highest catalytic activity among them, the COD removal efficiency of which can reach 91.31% in 30 minutes., authors=null,

articleAbstract=以CeO2作为改性添加剂、γ-Al2O3为载体、CuO为活性成分,用分层浸渍的方法制备出负载型CuO-CeO2/γ-Al2O3湿式氧化催化剂;采用TG-DTA、XRD对其进行表征,研究了Ce的掺杂对载体及活性成分高温稳定性的影响并得出结论:在湿式氧化反应过程中,Ce的掺杂有效抑制了γ-Al2O3向α-Al2O3转变的高温相变,以及活性成分CuO与载体间相互作用形成CuAl2O4的过程。通过对苯酚的湿式氧化降解实验,获知CeO2的加入可明显提高催化剂活性,其中6%CuO-6%CeO2/γ-100%Al2O3的质量组分比对苯酚的催化活性最佳,反应30min,苯酚溶液COD的去除率为91.31%。,
