An ultrahigh-loading single-site Zn catalyst for efficient and ambient hydrogen generation from silanes.

A nitrogen-doped carbon-supported ultrahigh-loading single-site Zn catalyst (Zn 1 -N-C, 28.3 wt%) was facilely constructed by using a ball milling strategy. With atomically dispersed ZnN 3 O sites, the catalyst showed superior catalytic properties for the generation of H 2 from silane/alcohol pairs, and scale-up and recycling tests demonstrated its great potential in practical applications.
