| 摘 要： | 以Pd-Cu／TiO2为催化剂，采用催化加氢技术进行脱氮研究．结果表明：TiO2载体的特性对催化活性及N2选择性有显著影响，与773K和973K温度下焙烧得到的载体相比，以573K温度下焙烧得到的TiO2为载体制备的Pd（5wt％）-Cu（1．25wt％）／TiO2催化剂可显著提高催化效率及N2选择性．

| Abstract: | In this study, catalytic hydrogenation using Pd-Cu/TiO_2 as the catalyst w as adopted to remedy the simulated groundwater which was polluted by nitrate. Re sults showed that the properties of TiO_2 support markedly influenced the catalytic activity and N_2 selectivity of Pd-Cu/TiO_2 catalyst. Pd (5wt%)-Cu(1.25wt%)/TiO_ 2 with TiO_2 calcined at 573K as the support showed an enhanced activity and N_2 selectivity compared with those with TiO_2 calcined at 773K and 973K. |
