要旨:
Recently discovered amorphous silica-based nanotubes (SBNTs) forming 3D hyperbranched assemblies were studied with transmission electron microscopy. The chemical composition and the element distribution in these template-free synthesized SBNTs were analyzed in depth at the nanoscale with energy-dispersive X-ray and electron energy loss spectroscopy. Furthermore, the bonding behavior of the elements Si, O, N, and P was examined. The SBNTs show a better resistance to extreme pH conditions than pure amorphous silica nanotubes. This is most likely due to the incorporation of N and P in the SBNTs.
