Universiti Alkane isomerization into its equivalent branched isomers has gained numerous attention as a reaction to obtain high quality fuel. In this study, platinum and molybdenum oxide supported on mesostructured silica nanoparticles (Pt/MoO3/MSN) was prepared via impregnation method and tested for n-pentane and cyclohexane isomerization. Mesoporous silica nanoparticles are promising materials for various applications, such as drug delivery and catalysis, but the functional roles of surfactants in the formation and preparation of mesostructured silica nanoparticles (MSN-as) remain to be seen. Rose Bengal (RB), a xanthene dye, incorporated into mesostructured silica nanoparticles (MSNs) exhibits efficient singlet oxygen ((1)O2) generation when illuminated with 540 nm green light which is particularly promising for PDT applications. Several systems with different RB loadings were synthesized and fully characterized by means of spectroscopic techniques in combination with a Abstract This study reports an efficient method for the preparation of well-dispersed ruthenium nanoparticles of controlled size loaded into micelle-templated silica (MTS).
Current approaches take advantage of mesostructured silica nanoparticles (MSNs) as carriers but suffer several problems including complex synthesis that requires sequential steps for (1) removal of surfactants and (2) functionalization of MSNs to allow Ultraporous mesostructured silica nanoparticles.

Through appropriate design and synthesis, multifunctional mesoporous silica nanoparticles for sophisticated bio‐applications are created. Silica, mesostructured (MCM-41) is a part of low-density organized mesoporous silicate system which has a 2D hexagonal phase, prepared in the presence of quaternary ammonium halide surfactant. It has ordered and large pores with diameter in the range 1.5-10 nm and specific surface area of 1500 m 2 /g. Pure mesoporous silica nanoparticles were prepared according to published literature procedure. 3 The CTAB surfactant was removed by calcination at 550 °C for 5 h. Attachment of the ICPES linker was accomplished by suspending 100 mg of the calcined particles in 10 mL of a 10 mM solution of ICPES in dry PhMe and refluxing for 12 h under N 2 .

Synthesis and Characterization of Supramolecular Colloids
Attachment of the ICPES linker was accomplished by suspending 100 mg of the calcined particles in 10 mL of a 10 mM solution of ICPES in dry PhMe and refluxing for 12 h under N 2. Mesostructured silica nanoparticles (MSNs) were synthesized with the formation liquid crystalline phases of cetyltrimethylammonium chloride (CTAC) that served as templates for the in-situ polymerization of tetraethyl orthosilicate (TEOS) in alkaline conditions.

The N 2 physisorption results indicated that the introduction of Ni altered markedly the surface properties of MCM-41 and MSN. The TEM, H 2-TPR and IR adsorbed CO studies Abstract Mesostructured silica nanoparticles (MSN) and Ni loaded onto MSN (Ni/MSN) for the methanation of CO2 were prepared by the sol–gel and impregnation methods. Catalytic testing was conducted in the temperature range of 423–723 K under atmospheric pressure in the presence of H2. Ni supported on MSN was compared with others types of support such as MCM-41 (Mobile Crystalline … Rose Bengal incorporated in mesostructured silica nanoparticles: structural characterization, theoretical modeling and singlet oxygen delivery 2020-05-25 The surface of α-Fe2O3 nanoparticles was successfully coated with mesostructured silica templated by surfactant assemblies using cetyltrimethylammonium ions. By repeating the coating operation, it was possible to control the thickness of the mesostructured silica phase.
