摘要
通过溶胶凝胶法,分别制备了不同负载量的WO_3/SBA-15和WO_3-ZrO_2/SBA-15介孔材料,利用XRD、BET和TEM等表征手段对其进行表征,并对其光降解染料罗丹明B的活性进行比对研究分析。结果表明:Wx/SBA-15(x=20,30,40,50)和W_(40)Zry/SBA-15(y=3,5,7,9)均能在可见光下光降解罗丹明B,光催化活性W_(40)/SBA-15>W_(50)/SBA-15>W_(30)/SBA-15>W_(20)/SBA-15;引入ZrO_2后,光催化活性W_(40)Zr_5/SBA-15>W_(40)Zr_9/SBA-15>W_(40)Zr_7/SBA-15>W_(40)Zr_3/SBA-15。其中,W_(40)/SBA-15和W_(40)Zr_5/SBA-15的光降解效率最高,分别为73.4%和86.6%,ZrO_2的引入提高了光降解效率;同时,WO_3/SBA-15和WO_3-ZrO_2/SBA-15也具有很好的循环价值,可多次使用。
Different loadings of WO3/SBA-15 and WO3-ZrO2/SBA-15 are prepared by sol gel method anti characterized by XRD, BET, TEM . The activity of photodegradation of rhodamine B and the adsorption of ammonia ability are investigated. The results show that the rhodamine B is photodegraded easily by using W,/ SBA 15 （χ= 20,30,40,50） and W40Zry/SBA-15 （y=3,5,7,9）. Photocatalytic activity from high to low is W40/SBA-15〉 W50/SBA-15 〉W〉30/SBA-15〉W〉20/SBA-15,while doped into ZrO2, Photocatalytic activity from high to low become W40 Zr5/SBA-15〉 W4o Zr9/SBA-15〉 W40Zr7/SBA-15〉 W10Zr3/SBA 15. The rate of photodegradation with W40/SBA-15 and W40 Zr5/SBA 15 are 73. 4% and 86. 6% respectively. WO3/SBA-15and WO3 ZrO2/SBA-15 also have good cycle efficiency and the advantage of reusability.
