Support Engineering for the Stabilisation of Heterogeneous Pd P-Based Catalysts for Heck Coupling Reactions.

Herein we report the use of a supported Pd P catalyst for Heck coupling reactions. For the stabilisation of Pd P and Pd, as reference system, the silica support material was modified via phosphorus doping (0.5 and 1 wt % P).

A Supported Palladium Phosphide Catalyst for the Wacker-Tsuji-Oxidation of Styrene.

The substitution of pure metal particles by metal phosphides in catalysis represents a promising opportunity to lower the required metal quantity in the context of a sustainable use of metal resources. Herein we show the synthesis of palladium phosphide, Pd P, supported on silica, which is tested as catalyst for the Wacker-Tsuji-oxidation of styrene to acetophenone. The synthesized catalyst is characterized by PXRD, SEM-EDX, FTIR, ICP-AES and XPS measurements.
