acid, was effectively immobilized on TiO 2 , and the hybrid Ti0 2 was characterized by UV―vis, XPS, MALDI-TOFMS as well as TEM analysis. The hybrid Ti0 2 exhibits high reactivity for dehalogenation of various organic halides such as phenethyl bromide, benzyl bromide, and 1,1-bis(4-chlorophenyl)-2,2,2-trichloroethane (DDT) under irradiation with UV light at room temperature.
钴胺素衍生物cobyrinic acid 被有效地固定在TiO 2 上,并且通过UV-vis、XPS、MALDI-TOFMS 以及TEM 分析对杂化TiO 2 进行了表征。杂化TiO 2 在室温下紫外光照射下对苯乙基溴、苄基溴和1,1-双(4-氯苯基)-2,2,2-三氯乙烷(DDT)等各种有机卤化物的脱卤表现出高反应性温度。
