Abstract

Abstract: Both the utilization of naturally occurring compounds to prepare functional materials and the selective conversion of aldehydes with other reducible moieties (ORMs) are very attractive topics. Herein, we synthesized a novel porous material, hafnium phytate (Hf‐Phy), by using naturally derived sodium phytate as the building block. Hf‐Phy has plenty of mesopores centered around 11.8 nm. Hf‐Phy showed excellent performance for the transfer hydrogenation of aldehydes with ORMs by using 2‐propanol as the hydrogen source with high selectivities (95–100 %) for alcohols without reducing ORMs. Systematic studies suggested that the oxophilicity of Hf 4+ and the basicity and structure of Hf‐Phy contributed significantly to the excellent performance. Additionally, Hf‐Phy could be used over at least five cycles without any decrease in activity or selectivity. Abstract : The other haf : Porous hafnium phytate (Hf‐Phy) with mesopores ranging centered around 11.8 nm can be synthesized by using naturally derived sodium phytate as the building block and is very efficient and selective for the catalytic transfer hydrogenation of various aldehydes with other reducible moieties. Systematic studies suggest that the excellent performance results from the oxophilicity of Hf 4+ and the basicity and structure of Hf‐Phy.
