Abstract

A series of Ag2O/γ-Al2O3 nanocatalysts for direct dehydrogenation of methanol with various extents of Ag2O loading (0.5–15 wt%) were prepared by the wet impregnation method. The catalysts were characterized by XRD, TEM and N2 sorption. The catalysts were tested for direct dehydrogenation of methanol in a fixed-bed reactor at a relatively low temperature, 330 °C, using N2 as a carrier gas. The obtained results revealed that pure γ-Al2O3 exhibits quite poor selectivity toward formaldehyde (FA) formation (≈28%). On the other hand, the addition of Ag2O improves the catalytic activity of γ-Al2O3 where the catalyst with 10 wt% Ag2O exhibits 100% conversion of methanol with 100% yield of FA. Moreover, the catalyst with 1 wt% Ag2O achieved similar results at the reaction temperature of 370 °C.
