| 摘 要： | 在低温条件下制备在太阳光照射下具有高光催化活性的氧化铋/二氧化钛复合颗粒。并利用XRD、SEM、BET、XPS和DRS对其进行表征。结果表明：将二氧化钛纳米颗粒沉积在氧化铋表面可形成微-纳结构,使该复合材料表现出多孔性,并提高表面羟基的含量。因此,在太阳光的激发下,氧化铋/二氧化钛复合颗粒对4-氯苯酚的催化降解能力高于纯二氧化钛和P25。

| Abstract: | Bismuth oxide/titania, one interfacial composite semiconductor with high photocatalytic activity under solar light, was prepared at low temperature. The structure was characterized by X-ray diffractometry (XRD), scanning electron microscopy (SEM), brunauer-emmett-teller (BET), X-ray photoelectron spectroscopy (XPS) and diffuse reflection spectra (DRS). The results indicate that deposited titania nanoparticles on bismuth oxide surface have micro-nano structure, and this composite material exhibits porosity a... |
