The metaiodobenzylguanidine (MIBG) radiopharmaceutical, an analogue of norepinephrine, has been used to diagnose certain diseases in the cardiovascular system when radiolabeled with I. This radiopharmaceutical can also be used to treat tumors, such as neuroblastomas and pheochromocytomas, when radiolabeled with I. Its clinical use is often accompanied by a slow intravenous administration, where...

The catalytic activities of SBA-15 aluminosilica meso/macroporous monoliths (Si/Al = 72) and mesoporous powders (Si/Al = 70) have been investigated using batch Friedel–Crafts alkylation of single-ring aromatic compounds, including toluene, ethylbenzene, cumene, and styrene, with benzyl alcohol. The toluene alkylation activities of the meso/macroporous monolith catalysts were compared with nanop...

A protonated polyaniline-functionalized SBA-15 mesoporous silica nanomaterial (H(+)-PANI/SBA-15) with high surface area and ideal surface properties for the adsorption of anionic dyes is synthesized. Compared with the conventional emeraldine salt of polyaniline (H(+)-PANI), H(+)-PANI/SBA-15 has a significantly higher adsorption capacity for the anionic dye Orange G and is a more effective sorbe...

Sulfonic acid functionalized SBA-15 as a nanoporous acid catalyst was used in the synthesis of 2-Aryl benzoxazoles 4 by the condensation of 2-aminophenol 1 and benzoyl chlorides 2 under microwave irradiation in solvent free reaction conditions. The advantages of this methodology are good product yields (60-98%), being environmentally benign, short reaction times and easy work up.

The adsorption and activation of both CO2 methanol are mainly affected by the distance Lewis acid site, Zr4+, base, Zr4+/O2−, Zr-based catalysts. In this paper, Zr-incorporated SBA-15 (Zr-SBA-15) Zr-grafted (Zr/SBA-15) catalysts were prepared with different Zr environments, analyzed N2 adsorption–desorption isotherms, X-ray diffraction, UV-vis spectra, XPS. It was proposed that Zr-SBA-15 cataly...

Tuning the morphological and acidic properties of mesoporous molecular sieve materials is highly valuable for catalyst design towards reactions involving large molecules. In this work, a series Ga-containing SBA-15 ordered (OMMs) were synthesized following acid-free strategy. Ga-SBA-15 exhibits an acid amount 0.48 mmol/g, comparable to Al-SBA-15 (0.45 mmol/g). addition, it found that straight s...
