Abstract
En 中文
• XRD–CT maps steam– and Cs–induced phase evolution in intact CZA pellets. • Steam and Cs promotion accelerate Cu sintering during CZA catalyst activation. • High pressure favours Cu2O formation and loss of metallic Cu0. • Water–induced sintering is most severe at catalyst pellet edges.
