Cover Story: Aging is one of the key steps in the preparation of highly active Cu/ZnO-based catalysts for use in the production of methanol. An initially amorphous precipitate transforms into the crystalline precursor phase of zincian malachite, which is characterized by the periodic arrangement of Cu and Zn atoms and has proven advantageous for the quality of the final catalyst. However, aging generally takes between 30 minutes and multiple hours. In this study, we show that aging can be accelerated by more than 90 % when the freshly precipitated suspension is seeded with already aged zincian malachite crystals. Seeding did not alter the physicochemical properties of the aged precursor. Consequently, the catalyst performance in the synthesis of methanol from CO2, as well as from a CO/CO2 mixture, was identical to a catalyst from an unseeded preparation. View this paper
