higher activity. After doping Co, more oxygen vacancies generated. The catalyticactivity of LaFe1-xCoxO3 was remarkably enhanced. ARG could be completely degraded in LaFe0.90Co0.10O3/PMS system within 10 min. The degradation rate was 51 times higher than that in the porous LaFeO3/PMS system. The superior activity can be attributed to the oxygen vacancies and synergistic effect of Co and Fe, which
基于硫酸根的先进氧化技术被认为是从水中去除有机污染物的最有效方法之一。在这项研究中,通过溶胶-凝胶法合成了多孔共掺杂的LaFeO 3催化剂,并将其用于过氧单硫酸盐(PMS)活化以降解有机污染物。系统研究了催化剂用量,PMS浓度,溶液初始pH值和自由基清除剂对酸性红G(ARG)降解的影响。多孔LaFeO 3比传统LaFeO 3(7.83 m 2 / g和0.11 cm 3)具有更高的比表面积(27.62 m 2 / g)和孔体积(0.15 cm 3 / g)/ g),从而导致更高的活动性。掺杂Co后,产生更多的氧空位。LaFe 1-x Co x O 3的催化活性显着提高。在10分钟内,LaFe 0.90 Co 0.10 O 3 / PMS系统中的ARG可能会完全降解。降解速率比多孔LaFeO 3 / PMS系统高51倍。优异的活性可以归因于氧空位和Co和Fe的协同作用,这促进了PMS的活化并产生了SO
