An Au-FeO@mesoporous SiO nanoreactor with a multiyolks/shell structure was synthesized through a multistep method. In this nanoreactor, the spindle FeO and Au nanoparticles were inside the same mesoporous SiO shell as the yolks but in a noncontact manner. The noncontact synergistic effect between Au nanoparticles and the FeO spindle was studied with a Fenton-like reaction. The catalytic activity of the Au-FeO@mesoporous SiO nanoreactor to the Fenton-like reaction for the degradation of organic dyes was dramatically enhanced by the noncontact synergistic effect.
通过多步合成法合成了具有多蛋黄/壳结构的 Au-FeO@介孔 SiO2 纳米反应器。在该纳米反应器中，棒状 FeO 和 Au 纳米颗粒作为蛋黄位于相同的介孔 SiO2 壳内，但处于非接触状态。通过类芬顿反应研究了 Au 纳米颗粒与 FeO 棒之间的非接触协同效应。非接触协同效应对 Fenton 样反应中有机染料降解的 Au-FeO@介孔 SiO2 纳米反应器的催化活性有显著提高。
