From Coordination Complexes to Potential Heterogeneous Catalysts via Solid‐State Thermal Decomposition: Precursor, Atmosphere and Temperature as Tuning Variables

Solid state transformations of PdCl 2 , [PdCl 2 (PPh 3 ) 2 ], [Pd(PPh 3 ) 4 ], RuCl 3 ⋅H 2 O, [RuCl 2 (p‐cymene)] 2 and [RuCl 2 (PPh 3 ) 3 ] in three different atmospheres (N 2 , air and O 2 ) have been studied by heating to 1000 °C/1400 °C these palladium/ruthenium compounds. The products obtained this way have been characterized by X‐ray diffraction and its specific formulation has shown a strong dependence on the precursor complex, the atmosphere used and the temperature. Thus it is possible to obtain different materials x Pd(1‐ x )PdO and x Ru(1‐ x )RuO 2 with a variable x value ranging between 0 and 1 from complexes without PPh 3 ligand. The decomposition pattern displayed by complexes containing PPh 3 is clearly different, as metal phosphate is generated during the process.
