Recent Research from University of Kent Highlight Findings in Microporous and Mesoporous Materials (Direct sol-gel synthesis of doped cubic mesoporous SBA-16 monoliths)

By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Microporous and Mesoporous Materials have been presented. According to news reporting out of Kent, United Kingdom, by NewsRx editors, research stated, "Porous monoliths of a 3D cubic cage mesostructured silica (SBA-16 type) and of composites containing Co (5% wt.) and FeCo (5% wt.) nanophases dispersed in the SBA-16 type matrix were prepared following a templated-gelation method. Optically clear disk-shaped monoliths with diameter around 10 cm were obtained whose absorption spectra are tunable based on the composition."

Our news journalists obtained a quote from the research from the University of Kent, "Low-angle X-ray diffraction, N-2 physisorption and transmission electron microscopy show that the ordered mesoporous structure and high surface area are preserved after calcination at 500 degrees C and after reduction at 800 degrees C, indicating a very high thermal stability. X-ray absorption spectroscopy at the Fe and Co K-edges allowed us to identify the intermediate products before and after reduction. In particular, the formation of a nanophase of layered cobalt silicate hydroxide was determined in the Co containing sample calcined at 500 degrees C. This compound is easily reducible giving rise to a superparamagnetic nanocomposite containing pure fcc Co nanoparticles dispersed within the 3D mesoporous silica structure."

According to the news editors, the research concluded: "Extensive characterization points out that the proposed procedure is promising in the preparation of functional nanocomposites with adjustable magnetic and optical properties."
