摘要: Abstract The activity behavior of carbon monoxide and propene oxidation on Cu Cr catalysts was investigated by varying both the catalyst composition heat-treatment conditions. γ-Alumina supported CuO, 2 O 3 oxide were employed. treated heating at 300–900°C under oxidizing or reducing atmosphere. Calcined 700–900°C atmosphere, formation 4 spinel structure resulted in an enhanced not only for but also oxidation. On other hand, treatment a atmosphere produced sintered copper surface induced strong metal-support interaction that led to enhancement activity, Additionally, synergistic effect resulting from ligand effect, as species is closely associated with CuO species, occurs reaches maximum content about 10 wt.-% chromium 25 wt.-%.
