Exploring superparamagnetic and intercalated Ag quantum particles in manganese oxide/graphene oxide for rapid and scalable organic pollutant removal

Here, a facile two step interfacial mediated self–assembly method is adopted to prepare the Ag modified manganese oxide (AMO) / silver (Ag)/ graphene oxide (GO) nano-composite. In the initial step the Ag nanoparticles are formed on the surface of the GO layer by electrostatic self-assembly and in another step these Ag nanoparticles are used as the nucleating centers to grow spherical domes of AMO on GO surface. The intercalated silver nanoparticles play crucial role for enhancing the charge transport pathways. This composite system significantly improved the catalytic degradation of organic pollutants under simulated sunlight irradiation. Especially, the composite with an optimal GO content ( 0.75
