摘    要:采用Ce(NO3)3掺杂改性后的纳米TiO2粉末作为光催化剂(Ce-TiO2),研究了Ce-TiO2在可见光条件下光催化降解苯酚的过程,考察了Ce掺杂量、焙烧温度、焙烧时间、pH值以及催化剂用量等因素对苯酚溶液光催化降解过程的影响。结果表明:可见光照射下,当Ce掺杂量为1.00%、焙烧温度为700℃、焙烧时间为3 h、反应溶液pH值为5、催化剂投加量为1.0 g/L时,苯酚的去除率达到最佳,为35.8%。

关 键 词:纳米TiO2  Ce掺杂  可见光  苯酚

Abstract:Mineralization of phenol was investigated under visible light irradiation by using the catalyst cerium doped nano-TiO2(named as Ce-TiO2).Degradation of phenol in different reaction systems was discussed,and the influences of reaction conditions,such as phenol concentration,solution pH,catalyst dosage and reaction temperature were also evaluated.The catalytic results showed that 35.8% TOC removal of phenol were achieved under visible irradiation at a reaction condition of cerium doped amount of 1.00%,calcination temperature at 700 ℃,calcination time for 3 h,pH 5 and 1.0 g/L catalyst dosage.
Keywords:nano-TiO2  cerium doped  visible light irradiation  phenol
