The development of silver orthophosphate based ternary composite catalyst for the augmented visible light assisted photocatalytic abatement of toxic refractory pollutants was accepted. It was confounded that the synthesized catalyst effectively degrade toxic organic dyes including methylene blue (MB), methyl orange (MO), rhodamine B (RhB) and acid red 18 (AR 18) with complete decolourisation and above
接受了开发用于增强可见光辅助光催化消除有毒难处理污染物的正磷酸银基三元复合催化剂的开发。令人困惑的是,合成的催化剂可以有效地降解有毒有机染料,包括亚甲基蓝(MB),甲基橙(MO),若丹明B(RhB)和酸性红18(AR 18),并且具有完全脱色和90%以上的矿化度的特点。成功降解了2、4-二氯苯氧基乙酸(2,4-D)等有害农药,高毒杀虫剂乙酰乙酸盐和药物抗生素四环素。在这里,这是第一次报告La 2 O 3 / Bi 2 O 3掺杂的正磷酸银三元催化剂可在短时间内去除有毒的有机污染物,并具有出色的矿化作用。复合催化剂的更好的重现性和可靠的稳定性为使其成为未来应用的有希望的催化剂铺平了道路。
