Abstract
FTIR data from Re2O7/γ-Al2O3 metathesis catalysts indicate that a low Re contents ReO4 ions have predominantly reacted with basic surface OH groups, while at higher Re2O7 loadings they have also reacted with neutral and more acidic OH groups.
On phosphated γ-Al2O3 the phosphate has reacted with the more acidic OH groups on the γ-Al2O3; in catalysts based on this support, the ReO4 − ions have also reacted with the phosphorus-bonded OH groups already at low Re2O7 loadings, resulting in more active catalysts.
