Thank you for your question. If you have further questions, please let me know.

The second one is the breathing effect property of MIL-53Ga MOF. This MOF is flexible and that's why we determined a low surface area.

Thank you, Johana. That’s an excellent question. We have two explanations for this. The first one is the properties of Ga indeed. The intermediaries of the reaction with Ga are more stable than those with Al. The same comportment is observed for homogenous catalysts.
