• can be measured by different measuring techniques, such as infrared (IR) spectroscopy [2], NMR spectroscopy [3], thermal analysis [4][5][6] and indicator method [7], as well as the amine titration method [8] and temperature-programmed desorption of ammonia (NH3-TPD) [9][10][11]. H-form zeolites are

Gas sorption [14], wide-angle X-ray scattering (WAXS), i.e., powder X-ray diffraction (XRD), and IR spectroscopy [15] are commonly used as analysis tools for porous materials in

• average particle size. IR spectroscopy and thermal treatment: The dark colour of the powders leads to the assumption that the particles are contaminated with excess carbon, at least on the surface of the particles. Thus we applied IR measurements as a surface sensitive method in addition to the XRD method

The calculated molecular length of 1 (without the flexible PEO chains) amounts to 10 nm, which fits very well with the experimentally observed widths of the fiber of 11 ± 2 nm (AFM). The height of the fibers observed
