| 摘 要： | 采用溶胶-活性炭浸渍法制备了Bi-Ti-O体系光催化剂,并以XRD、SEM、UV-Vis DRS对其进行表征。以在紫外光照射下对甲基橙的降解评价其光催化活性,分别考察了不同Bi/Ti比及煅烧温度的影响。实验表明,其光催化性能由粒径、吸光性能等共同影响。煅烧温度的提高使其在紫外区吸光性能有所下降,光催化活性相应降低。随着Bi含量的增加,在500℃时其禁带宽度有增加趋势,其形貌也发生了较大变化。而温度的升高,也使样品逐渐烧结团聚,降低了其光催化活性。在Bi/Ti比为5∶5和7∶3,煅烧温度为500℃时,由于Bi2O3、Bi2Ti2O7和Bi4Ti3O12三相共生共存,其混晶效应使得在紫外区的吸收明显增强,相应地提高了光催化活性。
