An unreduced catalyst which contains, per 100 parts by weight of CuO, 40 to 130 parts by weight of ZnO, 2 to 50 parts by weight of Al2O3 and, optionally, 0.5 to 8 parts by weight of an oxide of Mn, Mo, V, Zr and/or an alkaline earth metal, and, also optionally, 2 to 80...
The current commercial production of methanol through the hydrogenation of the green-house gas CO2 relies on a catalyst consisting of copper, zinc oxide and aluminum oxide. Even though this catalyst has been used for many decades in the chemical industry
The synergistic effect of zinc and copper in Cu2O/ZnO nanoflake as a heterogeneous catalyst for theN-arylation of heterocycles with aryl halides and arylboronic acids in the absence of additional ligand in air were demonstrated. The catalyst was characterized by powder X-ray diffraction (XRD), ...
