文摘

Multifunctional Fe3O4@TiO2@Ag-Au microspheres (MS) are prepared. The MS exhibit excellent catalytic activity attached with in-situ SERS monitoring. They have good photocatalytic performance and reusability by magnetic separation. The FDTD simulation shows the significantly increases of the ‘hot spot’.
