Thermally stable iron based redox catalysts for the thermo-chemical hydrogen generation from water
Publication year: 2012Source:Energy, Volume 42, Issue 1Lee-hwa Song, Hyun Woo Kang, Seung Bin Park Redox materials with high thermal stabilities, comprising iron oxide with alumina were synthesized from ultrasonic spray pyrolysis method. Their catalytic activities towards the redox evolution of hydrogen from water were evaluated and compared with that of pure iron oxide, which decreased rapidly after 1 cycle due to its low thermal stability. The samples containing alumina sustained their total and relative hydrogen evolutions over three redox cycles, while maintaining their original surface morphologies, thus demonstrating their thermal stability.

Polycrystalline Alumina Slurry for Polishing
Saint-Gobain's 92400.20MIC12 Polycrystalline Alumina Slurry for C plane sapphire wafer polishing is a truly remarkable product. It replaces colloidal silica, SiO2, the traditional final polishing slurry used for many years on C plane sapphire wafers. This slurry can polish the sapphire wafers 2 - 3 times faster than colloidal SiO2, and it doesn't scratch the sapphire wafers, is much more easily cleaned from the wafers and the polishing machinery. Product Benefits. High purity alpha A12O3... |
