A new procedure is reported to synthesis mesoporous silica micro sphere for the first time. In these method two surfactants namely Span 80 and Tween 80 were used. Small angle X ray diffraction and N2 adsorption analysis shows the synthesized material has mesoporous property. The material has spherical morphology with 1-10 μm particle size. Beside the material found to have microcapsule property...

For the first time, functionalized mesoporous silica nanoparticles (MSNs) with dinuclear Schiff-base complexes were synthesized as attractive organic–inorganic hybrids and their capability investigated for loading antibiotic drugs immobilization of enzymes.

In the last decade, significant research efforts were devoted to obtaining materials with welldefined nanostructures for a wide range of applications (Hamley, 2003; Soler-Illia et al., 2002; Paul & Sharma, 2006). Mesoporous silica materials like M41S, HMS, SBAn, FSM, and MSU, among others, are a fairly new type of material that has pores in the mesoscopic range of 2–50 nm (Wan et al., 2007). Th...

M41S: A family of mesoporous materials including MCM41, MCM-48, and MCM-50 MSU-1,2,3,4: Michigan State University no. 1, 2, 3, 4, a series of wormhole mesoporous materials prepared in the presence of nonionic surfactants Pluronic: polyethylene oxide–polypropylene oxide triblock surfactant, (EO)m(PO)n(EO)m, for example, P123 = (EO)20 (PO)70(EO)20 SBA-x: Santa Barbara no. x, a series of mesoporou...

A novel method of preparing thermally stable zirconia-based mesoporous materials was developed. The zirconia-based mesoporous materials of 2D-hexagonal structure were prepared using zirconium sulfate as the zirconium precursor and cetyltrimethylammonium (CTMA) as the pore-directing agent with the aid of salt in the synthesis solution to reduce the sulfate content in the final product and signif...

Functionalized nanoporous materials have been developed recently as bio/chemical sensing materials. Due to the huge specific surface of the nano-materials for molecular adsorption, high hopes have been placed on gravimetric detection with micro/nano resonant cantilevers for ultra-sensitive sensing of low-concentration bio/chemical substances. In order to enhance selectivity of the gravimetric r...

1. 1. Well-ordered Mesoporous Materials FSM-16 and M41S materials with regularly ordered mesopore arrangements and narrow pore-size distributions were fi rst described in the early 1990s1),2), and the mesostructures of silica and various metal oxides have since attracted much attention from chemists and materials scientists because of emerging applications in catalysis, adsorption, sensors, and...

Phosphorus from excess fertilizers and detergents ends up washing into lakes, creeks, and rivers. This overabundance of phosphorus causes excessive aquatic plant and algae growth and depletes the dissolved oxygen supply in the water. In this study, aluminum-impregnated mesoporous adsorbents were tested for their ability to remove phosphate from water. The surface structure of the materials was ...
