Hydrothermal synthesis of MCM-22(P) was carried out with two different silica sources, colloidal silica (28%) and silicic acid with different gel composition. The synthesis was carried out in stirring and static conditions with different crystallization time. MCM-22(P) modified with swelling-sonication method resulted in swollen MCM-22, while alkali treatment yielded desilicated MCM-22. The materials were characterized by X-ray diffraction, low-angle XRD, FE-SEM-EDX, FT-IR, TGA, N 2 adsorption and NH 3-TPD analysis. The results revealed that MCM-22 has a layered sphere, doughnut like morphology and after modification, swollen and broken sphere was observed. Physicochemical analysis revealed that the materials' mesoporosity increased and acidity also changed. Energy dispersive X-ray analysis revealed the high amount of desilication in alkali-treated MCM-22(P).

Nano-crystalline copper ferrite (CuFe2O4) was prepared by co-precipitation method and physicochemically characterized by a few techniques such as powder X-ray diffraction (XRD), Raman, and Ultraviolet-visible spectroscopy. Its catalytic effect was...

The thermal decomposition of AP and NTO was investigated in the presence of rGO, a perovskite structured BaCuO3 catalyst, and composite rGO + BaCuO3 using DTA analysis. These catalysts highly decreased the decomposition peak temperature of AP and NTO compared to pure AP and NTO.
