The Periodic Table and Kinetics?

André Merbach, Lothar Helm

Mendeleev in his first publication ordered the chemical elements following an apparent periodicity of properties such as atomic volume and valence. The reactivity of the elements was only studied systematically many years later. To illustrate the systemati ...

Thermal activation and aging of a V2O3/WO3-TiO2 catalyst for the selective catalytic reduction of NO with NH3

Oliver Kröcher, Davide Ferri, Adrian Marberger, Rob Jeremiah G. Nuguid

Real-world vanadium-based catalysts for the selective catalytic reduction (SCR) of NO with NH3 are occasionally exposed to high temperatures, which can induce catalyst aging. In this work, a 2.0 wt% V2O5/WO3-TiO2 catalyst based on commercial WO3-TiO2 was l ...
