- W2289226861 abstract "在高温固相法制备K4Nb6O17的基础上,采用油水自组装合成复合光催化剂Ag＠ AgCl/K4Nb6O17,利用XRD、SEM、TEM、EDX、UV-Vis、PL、BET等多种手段对复合光催化剂的微观结构、形貌和性能进行了表征,并研究了可见光下降解亚甲基蓝（MB）的催化性能.研究表明,Ag＠AgCl的粒径约为20nm,均匀分散在二维层状结构K4Nb6O17的表面上;贵金属Ag纳米粒子的表面等离子体效应显著,对可见光的吸收范围从400nm 拓展到800nm;Ag＠AgCl（25% （质量分数））/K4Nb6O17 在可见光照射60min对亚甲基蓝的降解率为88.2%,远远高于单体Ag＠AgCl和K4Nb6O17的活性.循环实验证明催化剂具有较好的稳定性,同时对苯酚和罗丹明B（RhB）也具有一定的催化降解活性.淬灭实验表明自由基和空穴均为活性物种,并在此基础上提出降解机理." @default.
