【摘要】： 本文致力于TiO_2粉末光催化劑的摻雜改性研究。分別采用控制膠體合成法和溶膠-凝膠法制備了兩種不同摻鐵方式的TiO_2粉末,并用XRD、TEM、TG-DSC、BET、UV-Vis、FS等技術(shù)對樣品進(jìn)行了表征。在紫外光照射下,以甲基橙溶液的光催化降解反應(yīng)為探針,研究了摻Fe離子濃度、包覆的次數(shù)、不同摻雜方式對樣品光催化活性的影響。研究表明: (1)摻雜離子的濃度對TiO_2晶相和顆粒粒徑有很大影響。500℃煅燒時(shí)樣品均為銳鈦礦相;在適量摻雜濃度下,摻入金屬離子能不同程度地抑制TiO_2晶粒的長大。本實(shí)驗(yàn)按方案A和方案B采取的非均勻摻雜樣品的粒徑相比相對應(yīng)的均勻摻樣品基本保持不變。 (2) BET結(jié)果顯示,所制備樣品均具有介孔結(jié)構(gòu),相比于均勻摻雜的TiO_2,按方案B采用控制膠體合成法制備的非均勻TiO_2,其比表面明顯增大。但隨著包覆次數(shù)的增多,比表面沒有明顯地變化。 (3)盡管摻雜方式有所不同,TiO_2粉末的光吸收帶邊隨著摻雜離子濃度產(chǎn)生紅移,并在可見光區(qū)吸收增強(qiáng)。另外,采取方案A和方案B,隨包覆次數(shù)的增多,都可以看到一個(gè)向短波長方向微弱的藍(lán)移現(xiàn)象。 (4) FS結(jié)果可以看出,圖中均勻摻雜的TiO_2的熒光強(qiáng)度比純TiO_2要低。另外,采取不同摻雜方式、摻雜濃度得到的摻鐵TiO_2的熒光峰的位置基本一致,說明摻入的Fe3+并沒有引起新的發(fā)光現(xiàn)象。 (5)采用均勻摻雜方式對TiO_2進(jìn)行摻雜改性,產(chǎn)生具有的最佳摻雜濃度,但TiO_2催化性能的提升效果不明顯,甚至?xí)档推浯呋钚浴＿@是由于均勻摻雜時(shí),金屬離子捕獲光生電子或空穴的同時(shí)又可能成為表面電子-空穴對的復(fù)合中心,從而降低TiO_2的催化活性。 (6)按方案A非均勻摻雜方式,當(dāng)加水量為0.5 ml左右時(shí)(接近化學(xué)計(jì)量值0.455ml),包覆一次后,得到的TiO_2催化劑的光催化效果最好,其中以0.02%Fe-TiO_2樣品作載體,包覆一次后得到的1-0.02%Fe-TiO_2/C-A具有最佳的光催化活性,其表觀速率常數(shù)分別為對應(yīng)的含有相同摻雜濃度的均勻摻雜的0.016%Fe-TiO_2的2.08倍,為純的TiO_2的2.73倍。 (7)按方案B非均勻摻雜方式,當(dāng)載體的摻雜濃度小于0.02%,n-FeTiC-B的催化活性不高。當(dāng)載體的摻雜濃度高于0.02%,相比FeTiE和未摻雜的TiO_2,n-FeTiC-B光催化活性明顯提高,并且隨著包覆次數(shù)(≤3次)的增加而增大。以干凝膠粉末0.04%Fe-TiO_2-G作載體包覆3次后制備的樣品具有最佳光催化活性,其表觀速率常數(shù)是純TiO_2粉末的5.32倍,是具有相同F(xiàn)e含量的均勻摻雜TiO_2粉末0.023% Fe-TiO_2的4.58倍。
