钒改性催化剂的制备及表征

Preparation and Characterization of V-Modified Catalyst

为了提高废水处理的效果,文章以高岭土为载体,制备了负载型的钒改性高岭土催化剂,并通过X射线单晶衍射、傅立叶红外光谱、扫描电子显微镜等手段对催化剂进行了表征,结果表明:高岭土经改性后,高岭土中的Al-O八面体结构部分被破坏,导致结构无序化,高岭土的层间距和比表面积显著增大,改性后的催化剂负载铁离子时催化效果较好。

V-modified kaolin was prepared using kaolin as the starting materials. XRD, FTIR, SEM are used to character the V- modified kaolin. The results indicated that, the V- polyeations are introduced into the layer of kaolin and such materials show enhanced basal spacing, and surface are stability.
