| 摘 要： | 用蔗糖溶液浸渍法制备碳掺杂改性二氧化钛(C/TiO2)光催化剂,考察催化剂在苯酚氧化降解反应中的活性,研究了焙烧温度、碳负载量等因素对活性的影响,以XRD、BET、UV/Vis漫反射光谱等方法对催化剂进行表征。结果表明,焙烧温度、炭的含量和粒径大小影响C/TiO2催化剂对苯酚的降解活性。其中当负载量为5%(mC/mTiO2),焙烧温度为500℃时,催化剂活性最高,150 min后苯酚的降解率达90%,高于商品化的催化剂P25。

| Abstract: | Carbon-doped TiO2(C/ TiO2) was prepared by impregnating with sucrose solution.The catalysis activity in oxidative degradation of phenol has been investigated.Effects of carbon content and calcined temperature on activity of the catalyst have been studied.Catalysts were characterized by XRD,BET and diffuse reflection UV/Vis spectroscopy.Studies show that the calcined temperature,carbon content and particle size of catalysts influenced the phenol degradation activity.Among this,carbon-doping would increase th... |
