Popis: Several Cr 2 O 3 /ZnO catalysts were prepared via co-precipitation with either K 2 CO 3 or (NH 4 ) 2 CO 3 and subsequently characterized by X-ray diffraction (XRD), N 2 -BET, and activity for methanol synthesis at 593 K. XRD and BET analyses of samples prepared with (NH 4 ) 2 CO 3 after calcination in dilute O 2 from 473 to 973 K revealed that mixed Cr 2 O 3 /ZnO materials (for which Cr/Zn
