How do structure and topology of the catalyst affect water promotion or inhibition effects?

In this activity article, team members of Yanhui Yang (professor at the School of Chemistry and Molecular Engineering at the Nanjing Tech University) and Daniel E. Resasco (professor at the School of Chemical, Biological, and Materials Engineering at the University of Oklahoma) elaborate on the decisive role of the structure and topology of the catalysts in the promotion effects of water in the catalytic reactions.
