利用水合肼还原法制备Cu2O，并向溶液中投入TiO2粉末的方法制备的催化剂改性的沥青基活性炭纤维(ACF-1)，与经过水合肼还原法制备的Cu 2 O ，溶胶凝胶法制备的TiO 2混合的催化剂改性的沥青基活性炭纤维(ACF-4)，在反应设备中进行吸附脱除NO实验对比，证明前者吸附效率高而选择ACF-1进行下一步调整，水合肼还原法制备Cu 2 O过程中，先后对TiO 2投入量的不同，和ACF负载时间不同进行调节，在反应设备中进行脱除NO实验，最后选定由Ti：Cu=0.5：1，负载时间为50min条件下制备的催化剂改性的沥青基活性炭纤维(ACF-1)，并对ACF-1与ACF-4进行XPS表征，分析改性前后ACF表面元素含量和官能团的变化。研究表明，改性后ACF表面官能含量增加，增强了ACF对NO吸附能力，使脱硝效率达61%。

The catalyst which is made by putting the TiO2 powder into the Cu2O solution is used to modify the activated carbon fibers(ACF-1), compared with the one made by the suspension of prepared TiO2 and prepared Cu2O(ACF-4). Then the removal efficiency of NO by the ACF after modification was investigated, it proves that the denitration of ACF-1 is better than the other one,so select ACF-1 for next adjustment. During the process of preparing Cu2O, the TiO2 inputs volume, and ACF load time are all the variable of the experiment. different for regulation. Finally selected the catalyst under the conditions of Ti:Cu=0.5:1, load time for 50min to modified activated carbon fiber (ACF-1), and XPS characterization is used to construct the different of surface functional groups between ACF-1 and ACF-4. The result shows that tne surface functional groups has increased after modified, which enhanced the denitration efficiency up to 61%.
