Beschreibung

Recently introduced flame based approach offers unique opportunities for advanced metal oxide nanostructuring, ranging from quasi 1D nanowires to macroscopic 3D porous interconnected tetrapodal networks.[1] The present strategy offers direct integration of ZnO nano- and microstructures and their networks on the desired substrates for various applications, e.g., whispering gallery modes, photocatalysis or nanosensing (UV/gases) applications.[1-4] The flame grown ZnO tetrapods ZnO nano- and microstructures exhibit very low cytotoxicity and they have shown strong potentials against antiviral applications.[5] The unique 3D shape of the ZnO tetrapods facilitates them to be used as efficient fillers for fabricating advanced composites, e.g., self-reporting composites[6] and many others. The 3D porous, flexible and conducting network from ceramic materials are now-a-days very important because of their technological relevance and the developed flame method offers desired synthesis of various ZnO and SnO2 nanonetworks.[1] These 3D porous networks can be decorated with other nanostructures for designing hybrid multifunctional materials[7] and can also be used as sacrificial templates to grow new nanomaterials.[8,9] Additionally, polymers can also infiltrated within the network to make different polymer based composites and template can be removed later on, if needed, to develop porous polymers.[10] An overview about the possible nanostructuring opportunities by the flame method will be presented and few application examples will be discussed.
