Facile and Continuous Synthesis of Ag@SiO2 Core–Shell Nanoparticles by a Flow Reactor System Assisted with Homogeneous Microwave Heating

Ag@SiO2 core–shell nanoparticles were synthesized by integration of a series of flow processes including microwave (MW)-assisted Ag nanoparticle formation followed by coating with SiO2 shell. TEM monitoring of the reaction intermediates revealed that two reaction pathways take place concurrently dur...

Description
Summary:Ag@SiO2 core–shell nanoparticles were synthesized by integration of a series of flow processes including microwave (MW)-assisted Ag nanoparticle formation followed by coating with SiO2 shell. TEM monitoring of the reaction intermediates revealed that two reaction pathways take place concurrently during the SiO2 shell coating. MW heating (70 °C, 1 s) remarkably reduced the SiO2 shell-formation reaction time.
