摘要：Pd/In2O3 catalysts with highly dispersed Pd species are prepared via a solid-state routine based on room-temperature grinding. Pd species can serve as the active sites for H-2 dissociation, thereby providing abundant H adatoms for CO2 hydrogenation. The addition of Pd significantly improves the catalytic activity of In2O3 for CO2 hydrogenation to methanol. In particular, 2 wt% Pd/In2O3 achieves a methanol space-time yield of 331.7 g(MeOH )kg(cat)(-1) h(-1) at 280 degrees C, 3 MPa, and 21,000 mLh(-1)g(cat)(-1), 3.6 times that of pure In2O3. [GRAPHICS] .
