- W2345133038 abstract "采用浸渍法制备Cu-Fe/TiO2-Al2O3催化剂,探讨了制备过程中前驱液铜铁比例、焙烧温度、焙烧时间等对催化剂活性的影响,并考察了Cu-Fe/TiO2-Al2O3催化光芬顿对喹啉废水的处理性能。结果表明,催化剂制备前驱液铜铁比例过高会抑制催化剂的活性,适量增加焙烧温度和焙烧时间有助于提高催化剂在光助非均相芬顿氧化体系中的催化性能。当前驱液Cu、Fe摩尔比1：5、焙烧温度200℃、焙烧时间5 h时所制备的催化剂性能为优。Cu-Fe/TiO2-Al2O3可以拓宽光芬顿反应的p H范围,在中性条件（p H=6.7）下较Fe/TiO2-Al2O3对喹啉的降解有较大提高,反应120 min后去除率分别为94%和58%。Cu-Fe/Ti O2-Al2O3在光芬顿体系中稳定性较好,可重复利用。表明Cu-Fe/TiO2-Al2O3是一种具有应用前景的高效光芬顿催化剂。" @default.
