摘要:
以钛酸四丁酯为前驱体、碘酸钾为碘源,粒状活性炭为载体,采用水热法和浸渍烧结法合成了I-TiO2/AC负载型催化剂.采用XRD、XPS、EDS等手段对催化剂进行表征.以苯酚为目标物,研究了不同种催化剂对苯酚的吸附效率及不同经浸渍-烧结处理的次数的I-TiO2/AC催化剂在可见光下降解苯酚的效率.实验结果表明:采用浸渍结烧法I-TiO2成功负载在活性炭上.由于活性炭和I-TiO2催化剂的协同作用,I-TiO2/AC催化剂对
Abstract:
I doped T iO2 pho toc ata lysts we re fabricated by hydrothe rm alm ethod, using tetrabuty l titanate as precursor, po?? tassium iodate as doping sources and then I??doped T iO2 photocata ly sts w ere immob ilized to g ranu lar activa ted carbon w ith them esh num be r of 20 to 40 ( 0??9 mm - 0??45 mm ) by soaks??s inter ing pro cess. The ca talysts we re cha racte rized by XRD, XPS, EDS. The adso rption effic iency of pheno l and the deg rada tion efficiency under sim ulated sunlight by IT iO2 /AC of d ifferent load ing tim es were investig ated. The resu lts show ed that I??doped T iO2 was successfully imm obilized to g ranu lar activated ca rbon, the adsorption effic iency of pheno l by I- T iO2 /AC reached 95??8% and degrada tion effi?? c iency o f pheno l unde r simu la ted sunlight by I- T iO2 /AC came to 64% .
