Preparation and Characterization of Mesoporous Ceramic Materials

Preparation and characterization of multifunctional magnetic mesoporous calcium silicate materials

We have prepared multifunctional magnetic mesoporous Fe-CaSiO3 materials using triblock copolymer (P123) as a structure-directing agent. The effects of Fe substitution on the mesoporous structure, in vitro bioactivity, magnetic heating ability and drug delivery property of mesoporous CaSiO3 materials were investigated. Mesoporous Fe-CaSiO3 materials had similar mesoporous channels (5-6 nm) with...

Preparation of silicotungstenic acid-containing mesoporous materials.

Silicotungstenic acid (STA)-containing mesoporous materials were directly synthesized in a nonaqueous medium by sol-gel method. X-ray powder diffraction showed that both as-synthesized and calcined materials possess mesoporous structure. STA contents in extraction solutions were analyzed with inductively coupled plasma. When STA/silica ratio changed from 1:100 to 1:4, the immobilization of STA ...

Preparation and Catalytic Properties of Ti-SBA-15 Mesoporous Materials

Ti-SBA-15 mesoporous materials were directly synthesized via a hydrothermal process and characterized by using nitrogen adsorption-desorption measurements, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, diffuse reflectance ultraviolet-visible spectroscopy, and infrared ray spectroscopy. The effect of synthesis temperatures on the structure and catalytic effic...

Chemical Precipitation of BaCeO3 – CeO2 Based Nano-ceramic Composite Oxide Materials and Their Physical Characterization

In order to reduce the operating temperature of solid oxide fuel cells (SOFCs), novel electrolyte materials based on CeO2 and BaCeO3 are being developed in the scientific realm. In this context, we propose a new methodology for preparing the nano-ceramic composite materials such as BaCe0.9Gd0.9O3-δ – Ce0.9Gd0.9O2-δ (BCGO–CGO) and BaCe0.8Sm0.2O3-δ – Ce0.8Sm0.2O2-δ (BCSO – CSO) as possible elec...
