Abstract: Formation of the structure in a copper-zinc catalyst for methanol synthesis is analyzed at each step of its preparation including hydrogen activation at which catalytically active species are formed. The necessary interaction of the catalyst components in fresh precipitates is provided by formation of mixed copper-zinc hydroxocarbonates. On low-temperature calcination, the interaction is preserved due to the formation of mixed copper-zinc oxides modified by OH- and CO32- anions with copper ions distributed as clusters in a zinc oxide-type structure. The activation with hydrogen results in formation of a proton-stabilized system of zinc oxide with epitaxially bound metallic copper. Both the chemical bond cleavage and spatial phase segregation at any step of the catalyst preparation result in the loss of its catalytic activity.
