Comparison of olefin metathesis by rhenium-containing γ-alumina or silica–aluminas and by some mesoporous analogues

Autor: Paul Célestin Bakala, Jean-Yves Piquemal, Jean-Marie Brégeault, Yannick Millot, Emmanuel Briot

Publikováno v: Journal of Catalysis. 258:61-70

Oxide materials with rhenium(V) oxochloro complexes highly dispersed on the surface were prepared by grafting Re(V) alkoxochloro complexes onto γ -Al 2 O 3 , chlorinated alumina, 25 and 75 wt% SiO 2 silica–aluminas, mesoporous alumina with high sp

Publikováno v: Catalysis Communications. 8:1447-1451

Silica-supported molybdenum oxide materials have been prepared by using the ability of molybdenum oxoperoxo complexes to interact with the surface hydroxyl groups of the support, which after calcination, have a highly dispersed MoO x /SiO 2 structure
