摘要
Aluminum-stabilized copper colloids with a size of about 5 nm (see picture) are the key to a quasi-homogeneous version of the heterogeneously catalyzed synthesis of methanol from synthesis gas over Cu/ZnO/Al2O 3. The catalyst productivity is very high in spite of the absence of ZnO. (Figure Presented). © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
