• were determined with an X-ray diffractometer with Cu Kα radiation (k = 0.15405 nm, 40 kV, 100 mA) over the 2-theta angle range of 10–70 °C with a scanning rate of 10 °C/min. The TGA data was obtained by a DSC-STA 449C Jupiter thermal analysis instrument. About 4 mg sample in an aluminium pan was heated

• 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

• formed during the nucleation stage are composed of hexagonal unit cells which can induce anisotropic growth along the c-axis, and thus hexagonal shaped nanocrystals with 1D structure are favored [24][25]. Thermal analysis The thermal behavior was studied in detail and is depicted in Figure 8. From the TG

• . The one-dimensional hexagonal rod structure, with regular arrangement and preferred orientation, was observed in SEM, TEM and HRTEM images. From EELS, the O-K edge and Mo-M2,3 peaks confirmed the existence of molybdenum and oxygen. From thermal analysis, the structural transformation from hexagonal to

• were observed by thermal gravimetric (TG), differential thermal gravimetric (DTG) and differential thermal analysis (DTA). The optical properties of h-MoO3 were studied by DRS and were recorded by means of a computer controlled T90+ UV–vis spectrophotometer. A BaSO4 plate was used as a reference (100
