A surface-chemistry study of barium ferrite nanoplates with DBSa-modified surfaces

- The surface chemistry of BaFe12O19 nanoplates was studied with XPS, SPEM and SIMS.
- The surface chemistry of nanoplatesdeviates from the bulk BaFe12O19.
- The SPEM enabled specific analyses of the basal and side planes of the nanoplates.
- DBSa is adsorbed on basal and side planes of the nanoplates.
- DBSa may be chemically bonded to the nanoplates via the bridging oxygen.
