Ceria-supported Pd catalysts with different size regimes ranging from single atoms to nanoparticles for the oxidation of CO

Kexin Ma et al.

Summary: Supported metal catalysts are widely used in industrial processes, and the size of the metal particles is crucial for the catalytic performance. This study investigates CeO2-supported Pd catalysts with different Pd size regimes and reveals that single Pd atoms supported on CeO2 have the highest intrinsic activity in CO oxidation and promote the CO-PROX reaction due to a stronger H-spillover effect.

Boosting Support Reducibility and Metal Dispersion by Exposed Surface Atom Control for Highly Active Supported Metal Catalysts

Myeong Gon Jang et al.

Summary: In this study, the activity and selectivity of oxide-supported metal catalysts were enhanced by controlling the catalyst's facet and doping methods. The WGSR activity of Pd supported on Cu-doped CeO2 (CDC) was found to synergistically increase, exceeding the sum of the effects of morphology and Cu doping. The effect of each tuning method on the activity was further investigated from a mechanistic perspective.

Understanding the Role of Boron on the Interface Modulation of thePd/TiO2 Catalyst for Direct Synthesis of H2O2

Shijie Liu et al.

Summary: Rational modulation of metal-support interaction by doping boron atoms at the interface of Pd and TiO2 is an effective strategy to enhance the catalytic performance of a supported catalyst for direct H2O2 synthesis. The boron doping increases the selectivity and productivity of H2O2 by enhancing the strong metal-support interaction between Pd and TiO2, leading to changes in the Pd2+/Pd0 ratio and surface Pd atoms configuration. The doped boron atoms provide more active sites for O2 activation and improve H2 adsorption and activation, resulting in simultaneous increases in H2O2 selectivity and productivity.

Evolution of Pd chemical states and effects of C3H6 and H2O on the CO oxidation over Pd/CeO2 catalyst

Mingzhi Wang et al.

Summary: The determination of dynamic changes in supported Pd catalysts during the CO/Hydrocarbons oxidation reactions is crucial for the development of efficient catalysts for vehicle exhaust purification. This study found that Pd/CeO2 catalysts, prepared by modulating the interaction between Pd precursors and CeO2 support, exhibited different dynamic properties under CO oxidation conditions, and also showed different deactivation behaviors in the presence of C3H6. The chemical states of Pd species on CeO2 during CO oxidation were found to correlate with their redox properties, which significantly influenced the role of C3H6 and H2O in the reactions.

Shiyuan Chen et al.

Summary: The structure of PdOx nanoparticles loaded on CeO2 nanocrystals of different shapes was systematically studied using Cs-corrected HRTEM/STEM, XPS, and Raman spectroscopy. The active sites for methane catalytic oxidation were found to be morphology-dependent on the CeO2 supports, with Pd2+ species identified as the active centers. Additionally, the chemical states of Pd can be tuned through interactions with CeO2 in oxidizing/reducing atmospheres.
