Abstract
CuO/ZnO catalysts, prepared in an automated synthesis by coprecipitation, were tested for methanol synthesis by high throughput screening using a 49-channel parallel flow reactor. The activity strongly depended on the preparation conditions and the calcination temperature. Interesting samples were selected for deeper characterization by EXAFS including in situ spectroscopic studies during temperature programmed reduction. Both ageing time and calcination temperature had a strong influence on the reduction behaviour of CuO/ZnO samples and thus resulted in an altered catalytic activity. In all cases, only a small fraction of Cu(I) species was formed during reduction.
