文摘
- •
Selective Cu@ZnOx core–shell catalysts of various compositions were synthesized.
- •
The catalytic sites are of the type CuxZn(1−x)Oy.
- •
A predictive model for determining the core–shell catalysts activity was developed.
- •
A correlation between activity and Zn migrated for three catalyst designs is shown.
