Pd-AlOOH/Al Honeycomb Monolith Catalysts Obtained from Pd(II) Complex Precursor with Different Ligands by a Facile One-Step Method

The adopted ligand type of a palladium precursor has a great influence on the microstructure, morphology and catalytic performance of obtained Pd-based monolith catalysts by a onestep method with redox reactions of two galvanic cells. In the sequence of ligand type NH3, en, Gly and EDTA, the obtained Pd-AlOOH/Al-x (x = NH3, en, Gly, EDTA) monolith catalysts showed gradually increasing specific surface areas, micro/ mesopore volumes and catalytic activities in toluene total oxidation reaction, because more AlOOH nanosheets and Pd nanoparticles were generated to form a more uniform and welldispersed three-dimensional-network structure film on the Al substrate surface.

Automated summary

The adopted ligand type of a palladium precursor plays a crucial role in the microstructure, morphology, and catalytic performance of Pd-based monolith catalysts obtained through redox reactions. Different ligands lead to varying specific surface areas, pore volumes, and catalytic activities in toluene oxidation reactions.
