The stability of Cu/ZnO catalysts in methanol synthesis is influenced by mass-transfer conditions of the calcination during catalyst preparation.
- class="label">•
Good mass-transfer conditions lead to high residual carbonate content and low crystallinity of the oxides.

Depending on the precursor structure differently bound residual carbonates exist in the oxides.
