Sol - gel synthesis of photoactive zirconia-titania from metal salts used for photodegradation
Catalysts : 14 May, 2014
Photoactive metal oxide systems capable of reducing non-biodegradable pollutants are highly needed heterogeneous catalysts for environmental purification. Most of the currently available heterogeneous catalysts are obtained from complicated synthetic routes using expensive and perhaps hazardous precursors. This study reports a novel sol–gel method to synthesize pure TiO2 and ZrO2–TiO2 samples using titanium oxychloride as TiO2 precursor and zirconyl nitrate hydrate as a ZrO2 source in the presence of the surfactant. The ratio of Zr-to-Ti was controlled between 0.75 and 3.2 to evaluate the effect of the amount of ZrO2 in the composites.
 
Inverse sigma transformation - a cut-and-paste method for making custom microporous materials
Catalysts : 26 November, 2012
Researchers at KU Leuven, Ghent University and the University of Antwerp have discovered a way - Inverse sigma transformation - to make new zeolites quickly.
 
New measurement technique helps catalytic converters with lower ignition temperatures
Catalysts : 05 November, 2012
What is the required operating temperature that an efficient automotive catalytic converter requires? Tiny metal particles require a minimum temperature, which, thanks to a new measuring technique, the Vienna University of Technology can now clarify. It should then be possible to build catalytic converters which take effect in cars as soon as possible after start-up.
