Piranhas haben scharfe Zähne und sind für ihren Appetit bekannt. Piranha‐Lösung, eine Mischung aus Schwefelsäure und Wasserstoffperoxid, ist wiederum eines der stärksten Oxidationsmittel für die Entfernung organischer Reste; ihre Verwendung für die Detemplatisierung und Exfoliation von MFI‐Nanoschichten beschreiben Q. Xiao, M. Tsapatsis et al. in der Zuschrift auf S. 7300 ff. Somit gelang die Herstellung...
Two‐dimensional zeolite nanosheets that do not contain any organic structure‐directing agents were prepared from a multilamellar MFI (ML‐MFI) zeolite. ML‐MFI was first exfoliated by melt compounding and then detemplated by treatment with a mixture of H2SO4 and H2O2 (piranha solution). The obtained OSDA‐free MFI nanosheets disperse well in water and can be used for coating applications. Deposits made...
