Enhanced adsorption and non-linear optical properties of DNA-CTAB functionalized mesoporous silica nanoparticles and their influence on enhancement of photoluminescence of Rhodamine 6G dye

AIP Advances, 2023
We report a novel template method for synthesizing silica nanoparticles that are mesoporous as well as biocompatible. The mesoporous silica nanoparticles were synthesized using the Stober process and peptization method.

Mesoporous silica spheres from colloids [PDF]

, 2007
A novel method has been developed to synthesize mesoporous silica spheres using commercial silica colloids (SNOWTEX) as precursors and electrolytes (ammonium nitrate and sodium chloride) as destabilizers. Crosslinked polyacrylamide hydrogel was used as a

Incorporation of Ag nanostructures into channels of nitrided mesoporous silica [PDF]

, 2008
Nitrided mesoporous silica was used as a host for accommodating nano-silver into the channels. The nitridation of the mesoporous silica host, i.e. SBA-15, with ammonia caused the generation of -NHx groups on the surface. The following impregnation of the

Environmentally Benign Bifunctional Solid Acid and Base Catalysts [PDF]

, 2014
Solid bifunctional acid–base catalysts were prepared in two ways on an amorphous silica support: (1) by grafting mercaptopropyl units (followed by oxidation to propylsulfonic acid) and aminopropyl groups to the silica surface (NH2–SiO2–SO3H), and (2) by ...

Sequestration of CO2 using Cu nanoparticles supported on spherical and rod-shape mesoporous silica

Journal of Saudi Chemical Society, 2018
The CO2 sequestration is one of the most promising solutions to tackle global warming. In this study, spherical mesoporous silica particles (MPS-S) and rod-shaped mesoporous silica particles (MPS-R) loaded with Cu nanoparticles were selectively prepared ...
