Abstract
Cashew nut-like zeolite NaP powders were synthesized using agro-waste material, rice husk ash as silica source via its in-situ extraction in the presence of other organic-free low cost precursors like aluminum foil, sodium hydroxide and water under hydrothermal condition at 100°C for 48h. The powders were characterized by thermogravimetry analysis (TGA), differential thermal analysis (DTA), powder X-ray diffraction (PXRD), Fourier transform infrared (FTIR) spectroscopy, N2 physisorption measurements and field emission scanning electron microscopy (FESEM). BET surface area and total pore volume of the powders were 129m2g−1 and 0.18cm3g−1, respectively. FESEM images showed cashew nut-like morphology of the powders, and Si/Al ratio of the powders was found to be 2.01 as indicated by the elemental analysis with energy dispersive X-ray (EDX).
