Engineering Heterogeneous Catalysis with Strong Metal-Support Interactions: Characterization, Theory and Manipulation

Tiancheng Pu et al.

Summary: Strong metal-support interactions (SMSI) is a classic yet fast-growing area in catalysis research. By regulating the interfacial interactions, SMSI phenomenon can encapsulate and stabilize metal nanoparticles, significantly impacting catalytic performance. Engineering SMSI provides a promising approach to steer catalytic performance and tackle energy and environmental challenges effectively.

Role of the Support Oxidation State on the Catalytic Activity of Two- Dimensional Pt/TiOX Catalysts

Gyuho Han et al.

Summary: The interaction between metal and support significantly enhances catalytic activity. In this study, the effect of the support's oxidation state on the metal-support interaction (MSI) in two-dimensional Pt/TiOx catalysts was investigated. Pt nanoparticles were deposited on titanium oxide supports with five different oxidation states using arc plasma deposition, and CO oxidation reaction was accurately performed in a batch reactor. It was confirmed that the catalyst with the highest oxidation state of the support exhibited the best catalytic activity. The Mars-van Krevelen mechanism at the metal-oxide interface was affected by the oxidation states of the supports, and the compositional effects of the support were confirmed by X-ray photoelectron spectroscopy analysis.

Single-Atom Catalysis: Insights from Model Systems

Florian Kraushofer et al.

Summary: The field of single-atom catalysis (SAC) has been expanding rapidly, but there is a significant disconnect between experiments and theoretical computations. It is challenging to determine the structure of active SAC sites due to the presence of multiple facets, surface sites, defects, and contaminants in powder supports. Experimental modeling can help understand plausible mechanisms. This review focuses on stable metal atoms on low-index surfaces of typical supports and explores the potential for expanding such studies to other relevant materials.

Tuning Strong Metal-Support Interaction Kinetics on Pt-Loaded TiO2 (110) by Choosing the Pressure: A Combined Ultrahigh Vacuum/Near-Ambient Pressure XPS Study

Philip Petzoldt et al.

Summary: In this study, the effect of O-2 and H-2 on Pt/TiO2(110) catalysts was investigated using synchrotron-based near-ambient pressure X-ray photoelectron spectroscopy. The results showed that the rate of formation of the encapsulating oxide layer on Pt particles varied with different O-2 pressures, and once encapsulation occurred, Pt particles remained embedded in the support.

Shaohua Xie et al.

Summary: The local coordination structure of metal sites plays a crucial role in the performance of supported metal catalysts. This study successfully fabricated Pt atomic single-layer structures with precisely controlled local coordination environment, which exhibited higher turnover frequency and improved catalytic activity in CO oxidation.

Tuning Strong Metal-Support Interaction Kinetics on Pt-Loaded TiO2 (110) by Choosing the Pressure: A Combined Ultrahigh Vacuum/ Near-Ambient Pressure XPS Study

Philip Petzoldt et al.

Summary: The study shows that O-2 and H-2 have a significant impact on the SMSI state of Pt/TiO2 catalysts, with encapsulating oxide layer forming more rapidly at low O-2 pressures, but less effectively at higher pressures. The oxidation/reduction of Pt particles is reversible, but once encapsulated, they remain embedded in the support.

Summary: The distance between supported metal nanoparticles plays a critical role in mitigating thermally induced sintering, as demonstrated in a study using carbon black supported platinum nanoparticles. By enlarging the particle distance beyond a critical value, particle coalescence can be significantly suppressed up to 900 degrees Celsius, showcasing the importance of metal-support interactions in preventing catalyst deactivation.

Photoemission spectrum in paramagnetic FeO under pressure: Towards an ab initio description

S. Di Sabatino et al.

Summary: In this paper, an exhaustive study of the photoemission spectrum of paramagnetic FeO under pressure using a refined version of the many-body effective energy theory (MEET) is provided. The MEET accurately describes the photoemission spectrum and spin configuration at ambient as well as high pressure, showing a transition from high-spin to low-spin configuration as pressure decreases. Additionally, comparisons with density-functional theory and GW methods for the antiferromagnetic phase are reported.
