Mesoporous silica metal oxide (ZnO and CdO) thin films have been used as metal ion precursors to produce the first examples of mesoporous silica metal sulfide (meso-SiO(2) @ZnS, meso-SiO(2) @CdS) or silica metal selenide (meso-SiO(2) @ZnSe, meso-SiO(2) @CdSe) thin films, in which the pore walls are made up of silica and metal sulfide or metal selenide nanoflakes, respectively. A gentle chemical...

Catalysts for methanol oxidation reaction (MOR) are at the heart of key green-energy fuel cell technology. Nanostructured Pt materials are the most popular and effective catalysts for MOR. Controlling the morphology and structure of Pt nanomaterials can provide opportunities to greatly increase their activity and stability. Ordered nanoporous Pt nanowires with controlled large mesopores (15, 30...

Ordered mesoporous carbons with various structures, designated as CMK-1~5, have been synthesized by carbonization of sucrose, furfuryl alcohol or other suitable carbon sources inside silica or aluminosilicate mesopores that are interconnected into three-dimensional networks such as in MCM-48 (cubic Ia3d), SBA-1 (cubic Pm3n) and SBA-15 (hexagonal p6mm). The mesoporous carbon molecular sieves, ob...

Mesoporous silica with KIT-6 structure was investigated as a preconcentrating material in chromatographic systems for ammonia and trimethylamine. Its adsorption capacity was compared to that of existing commercial materials, showing its increased adsorption power. In addition, KIT-6 mesoporous silica efficiently adsorbs both gases, while none of the employed commercial adsorbents did. This mean...

Large-pore mesoporous silica microspheres with tailored pore sizes were prepared via a two-step synthesis process by using a triblock copolymer EO20PO70EO20 as template in combination with a cosurfactant cetyltrimethylammonium bromide (CTAB) and a cosolvent ethanol. The obtained mesoporous silica spheres were characterized by scanning electron microscopy (SEM), transmission electron microscopy ...

"Carbon-based material" has demonstrated a great potential on water purification due to its strong physical adsorption to organic pollutants in the water. Three-dimensional cubic ordered mesoporous carbon (CMK-8), one of the well-known ordered mesoporous carbons, was prepared by using nanocasting method with mesoporous silica (KIT-6) as the template. In this study, CMK-8 blended with Nafion pol...

Sol-gel copolymer-templated mesoporous silica films with a thickness of 70 nm and interpore spacing of 4.34 nm were fabricated on gold layer covered glass substrates for application as a wavelength-interrogated surface plasmon resonance (SPR) sensor. The resonance wavelength (λ(R)) of the sensor with a solution sample was determined by absorptiometry at a given incident angle. A comparison betw...
