The wet impregnation of ammonium heptamolybdate onto silica–alumina is used to prepare MoO 3 /SiO 2 –Al 2 O 3 heterogeneous metathesis catalysts. The preparation is inspected in details in conjunction with physico-chemical characterization tools with the aim to identify the parameters that dictate the genesis of active and inactive metathesis species. The effects of...
MoO 3 /SiO 2 –Al 2 O 3 catalysts are prepared via flame spray pyrolysis and evaluated in the self-metathesis of propene to ethene and butene. Their specific surface area ranges between 100 and 170m 2 g −1 depending on the MoO 3 loading (1–15wt.%, corresponding to Mo surface density between 0.3 and 6.1Mo atoms per nm 2 ). The catalysts...
