本文利用溶胶凝胶法制备多壁碳纳米管负载TiO2及掺杂Cu/Mn的TiO2 (MWCNTs/TiO2,MWCNTs/CuTiO2及MWCNTs/Mn-TiO2).利用透射电镜(TEM),X射线衍射仪(XRD),X射线能谱仪(EDX)和紫外-可见分光光度计(UV-Vis)对制备的光催化剂进行表征.结果表明Cu/Mn掺杂的光催化剂TiO2晶相以锐钛矿为主,晶粒尺寸较纯TiO2降低.DRS图谱表明MWCNTs/TiO2光吸收边拓展至可见光区域,而10％ MWCNTs/Cu-TiO2及0.5％ MWCNTs/Mn-TiO2在紫外可见光区域都有较强的光吸收强度.用固定床反应器,对光催化剂的脱硫性能进行研究,MWCNTs/TiO2具有较强的光催化脱硫能力,10％ MWCNTs/Cu-TiO2及0.5％ MWCNTs/Mn-TiO2的光催化脱硫效率分别提高至71％和69％.
