Snowflake Porous Multi-Metal Oxide Nanocatalysts From Metallocene@Metal Organic Framework Precursors

We report a general approach to prepare 'snowflake' porous metal oxide nanostructured catalysts using tailored precursors consisting of metallocenes embedded within MOFs via thermal treatment under air. The resulting welt-dispersed multi-metallic nanocatalysts show improved activity for ammonia synthesis at low temperature.
