The activity of Cu/ZnO/Al 2 O 3 catalysts for methanol synthesis is determined by the microstructural arrangement of the oxides among other factors. A large metal/oxide interface area seems to enhance the intrinsic activity of Cu. A novel type of Cu/ZnO/Al 2 O 3 catalyst demonstrates the potential of this positive effect, which can outweigh the simultaneous loss of gas accessible Cu surface area in comparison to a conventionally prepared sample.
