Cationic tern plating with organic counterion for superstable mesoporous silica

Sulfonic Acid-Functionalized Lus-1: An Efficient Catalyst for One-Pot Synthesis of 2,4-Diamino Pyrimidine-5-Carbonitrile Derivatives

“…Vol. 39,No. 8 Then, LUS-Pr-SH (10 g) was oxidized with H 2 O 2 (50 mL) and one drop of H 2 SO 4 in methanol (10 mL) for 24 h at room temperature, then the mixture was filtered and washed with H 2 O and then acetone to obtain pure LUS-Pr-SO 3 H as catalyst.…”

“…Furthermore, due to the presence of more SiOH groups on the silica surface, LUS-1 will be able to react with more surface modifying groups. 8 Guanidine is a strongly alkaline and water-soluble compound that plays a key role in many biological activities. For example, guanidine affects on the neuromuscular transmission by modifying the release of acetylcholine from the motor nerve.…”

Potentiometric Detection of Mercury(II) Ions Using a Carbon Paste Electrode Modified with Substituted Thiourea-Functionalized Highly Ordered Nanoporous Silica

“…1 2,3 and SBA-15, 4 present a very high surface area, a uniform These new designed CPEs all had improved lifetimes compared open form structure and an extremely narrow pore size distribution. to those previously reported.…”

Application of Sulfonic Acid Functionalized Nanoporous Silica (SBA-Pr-SO3H) for One-Pot Synthesis of Quinoxaline Derivatives

“…The high ordered nanoporous silica, such as MCM-41 (Beck et al 1992), LUS-1 (Reinert et al 2003, Bonneviot et al 2001 and SBA-15 (Zhao et al 1998) are unique inorganic solid supports that have very high surface area with controllable pore sizes between 2 to 30 nm. They can be used as catalysts (Trong On et al 2001, Mohammadi et al 2007, for the preconcentration of metals (Ganjali et al , 2004, and as modified carbon electrodes (Badiei et al 2005, Zhang et al 2006, Walcarius et al 1999.…”
