Abstract. The effect of zirconia polymorphs on the activity and selectivity of V2O5/ZrO2 for the alkylation of phenol with methanol has been investigated. Relatively pure monoclinic zirconia (m-ZrO2) and tetragonal zirconia (t-ZrO2) were prepared. A series of vanadium oxide supported on m- and t-ZrO2 with varying vanadium oxide content from 2.5 to 15 wt% were prepared by wet impregnation me…
