Nano-stacked aluminum titanium silicalite-1(NS-AlTS-1) zeolite with MFI structure was prepared by direct synthesis using a microwave technique and also prepared the conventional aluminum titanium silicalite-1(AlTS-1) by conventional hydrothermal method for comparison. The morphological aspects of these materials were investigated with the help of SEM. The zeolite framework Al location was confirmed by 27Al MAS NMR. The existence of Ti species in the zeolite framework and its co-ordination environment was investigated by UV-Vis spectroscopy. The uni-model distribution of weak acidic sites was estimated by the well established NH3-TPD technique.
