Temperature-programmed reduction study on calcination of nano-palladium

Article Abstract:

The effects of calcination treatment on samples of mono-metallic Pd and Pd77-Ag23 alloy with primary particles around 8nm are studied with the temperature-programmed reduction technique. A consumption of hydrogen for PdO reduction and a subsequent desorption of hydrogen from bulk palladium hydride are observed.

Mathematical modeling of reactive phase separation in the system Rh(110)/K/)2+H2

Article Abstract:

A realistic mathematical model is presented which reproduces qualitatively correct and to a large part, even quantitatively correct the experimental results. The effect of an alkali condensation into stationary coadsorbate islands under reaction conditions has been successfully simulated with a realistic model.

Low-temperature-programmed replacement of nitrogen by hydrogen in pores of mordenite

Article Abstract:

The progressive replacement of nitrogen filled in the pores of NaMOR by hydrogen was studied by a specially designed low-temperature-programmed routine (LTR). Results stated that replacement profile comprised of four kinds of phenomena.
