Synthesis and Characterization of NaP zeolite@Fe3O4 /Am-Py as a Micro-Meso Structure

“…The second step, weight loss (4.7%) in 200-580 0 C attributed to NaP zeolite phase transfer [30]. The third step, weight loss (1.4%) in 580-900 °C, accompanied with endothermic peaks in DTG can be corresponded to the dehydration of the hydroxyl groups inside the micro and meso phases [31] and also changing in the structure of Fe 3 O 4 present in this region [32]. In the case of NaP zeolite@Fe 3 O 4 /Am-Py the percent of weight loss in the second steps increased about 3.7% due to thermal decomposition of the organic agent and also in the DTA curves two peaks endothermic can be seen which, the first peak about 200-300 0 C confirmed the presence of alkylamino pyridine in the structure [33].…”

Heteropoly acid/NaY zeolite as a reusable solid catalyst for highly efficient synthesis of gem-dihydroperoxides and 1,2,4,5-tetraoxanes

“…Recently, both natural and modified zeolites have been considered as effective heterogeneous catalysts in many organic reactions. 35,[36][37][38][39][40][41] These compounds have shown high catalytic efficiency and selectivity, and they have been recovered and reused for many runs. Lately, heteropoly acid/NaY zeolite (HPA/NaY), a hybrid catalyst, has been synthesised and utilised as an efficient catalyst for the synthesis of perimidines.…”
