XPS study of modifying layers on the surface of iron particles

Fast capture of methyl-dyes over hierarchical amino-Co0.3Ni0.7Fe2O4@SiO2 nanofibrous membranes

“…S6 (Fig. S7a), which indicated the strong bonding between NPs and SiO 2 fiber support were formed during the high temperature calcination 30 . By contrast, the Si-O-Fe peak was indiscernible from the Si2p spectra of the physical mixed SiO 2 fibers and Fe/Co/Ni oxides (Fig.…”
