The hydrothermal stability of Cu/beta NH 3 SCR catalysts are explored here. In particular, this paper focuses on the interesting ability of this catalyst to maintain and even enhance high-temperature performance for the “standard” SCR reaction af

Alloy particles were detected by XRD in bimetallic catalysts, made from physical mixtures of powders comprising distinct metal-support combinations (e.g., Pd on alumina and Rh on ceria-zirconia), following high-temperature redox aging. The morphology

Cerium concentrate, a mixture of ceria (about 60 wt.%) and other rare-earth (mostly lanthanum) oxides, partially transforms into a solid solution upon high-energy mechanical milling. Temperature-programmed reduction of the milled material resembles t
