Abstract

In its element: Zn ²⁺ at the M7 site of MFI-type zeolites activates H ₂, via ZnH and OH species, and leads to Zn ⁰ species. The Zn ⁰ species returns to its original state, a Zn ²⁺ ion, upon evacuation of the zeolite at 873 K (see picture). The formation of the Zn ⁰ species is supported by DFT calculations.
