Two series of samples were prepared namely Cr-Ti/MCM-41 and Cr/SiO 2 -TiO 2 keeping Si/Ti mole ratio same, with different Cr loading. The physico-chemical properties of the samples were characterized by different analytical techniques such as XRD, FT

MnAPO‐11 samples were synthesized from aqueous (MnAPO‐11(A)) and ethylene glycol (MnAPO‐11(NA)) media. The crystallinity of the samples was more when the synthesis was carried out in ethylene glycol. Chemical and thermogravimetric analyses reve

SAPO-39, a silicon-containing aluminophosphate molecular sieve analogous to AlPO4-39 and MAPO-39 (ATN topology, 4.0-A wide pore opening and tetragonal symmetry), was synthesized as a pure phase by hydrothermal crystallization from a gel with molar co

Characterization of MCM-22 was carried out by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermal analysis (TGA-DTA) and nuclear magnetic resonance (NMR). TGA-DTA and NMR studies indicate a strong interaction of the template with the

The thermal decomposition of mixed ZrMn oxide hydrates containing 0–0.3 mol of manganese was examined by means of simultaneous TG and DTA. When heated, these mixed hydroxides decompose to an amorphous oxide phase and subsequently crystallize to
