Reports from University of California Describe Recent Advances in Silicon

June 6, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Silicon. According to news reporting from Los Angeles, California, by NewsRx journalists, research stated, "We report on fabrication of highly porous silicon oxycarbide (SiOC) material, SixOyCz. The material possesses high surface area, a hierarchical pore size distribution, and an ordered layered structure."

The news correspondents obtained a quote from the research from the University of California, "We synthesized it using tri-isopropylsilane as a precursor, a layered double-hydroxide as a sacrificial template, and chemical vapor deposition at temperatures 700 degrees C and 800 degrees C. Several techniques, such as X-ray diffraction, X-ray photoelectron spectroscopy, and transmission and scanning electron microscopies, were used to characterize the morphology of the material, and is shown to be composed of hollow spheres with a layered interior. Nitrogen sorption validates the hierarchical structure of the material with both meso- and micropores. The material exhibits high BET surface area, ranging from 330 m(2)/g to 540 m(2)/g, and a total pore volume from 0.50 cm(3)/g to 0.91 cm(3)/g."

According to the news reporters, the research concluded: "It was fabricated using low-cost templates and precursors, as well as convenient synthesis procedures, and is a promising material for several applications, such as catalyst support, sorbents, and battery anodes."
