417Fe3O4@MoS2-Ag428.9nmOthersThe Fe3O4@MoS2-Ag composites were observed with MoS2 covering Fe3O4 (diameter of ~428.9 nm) by SEM and TEM images17.446The BET surface area was calculated to be 7.746, 13.464, 16.607 and 17.446 m2/g for MoS2, Fe3O4, Fe3O4@MoS2 and Fe3O4@MoS2-1%Ag, respectively, showing the superiority of MoS2 sheets vertically growing on Fe3O4.
