Abstract
Supported MoOx catalysts on oxide supports (Al2O3, TiO2, ZrO2, SiO2) were synthesized for propylene metathesis, characterized with in situ spectroscopies (DRIFTS, Raman, UV-vis) and chemically probed with propylene-TPSR, ethylene/2-butene titration.

Abstract
The enhancing effect of ZnO on the activity of Mo/SiO2 in the metathesis of ethylene with 2-butene is investigated. The strength of the effect depends on the reaction temperature and the manner in which ZnO and Mo/SiO2 are located in the reactor.
