Influence of framework Al density in chabazite zeolites on copper ion mobility and reactivity during NOx selective catalytic reduction with NH3

Siddarth H. Krishna et al.

Summary: In this study, Cu-CHA zeolites with different aluminum densities (0.2-1.7 Al/CHA) were investigated using statistical simulations, steady-state kinetics, and operando X-ray absorption spectroscopy. The results show that increasing the aluminum density leads to an increase in the fraction of Cu-I ions that are SCR active and the Cu-I oxidation rate constants, providing insights into how anionic Al centers in zeolite frameworks regulate the mobility of ionically tethered Cu cations and their dynamic reactivity during low-temperature NOx SCR.

Structure-activity relationship of Pt catalyst on engineered ceria-alumina support for CO oxidation

Shaohua Xie et al.

Summary: In this study, a novel Pt catalyst was prepared on a CeO2/Al2O3 support through a unique deposition strategy, demonstrating excellent thermal stability and low-temperature CO oxidation activity.

Surface Noble Metal Concentration on Ceria as a Key Descriptor for Efficient Catalytic CO Oxidation

Florian Maurer et al.

Summary: Increasing the Pt surface concentration can decrease the ignition temperature of CO oxidation and enhance the stability of the Pt/CeO2 catalyst. The improved reaction rate at higher Pt surface concentrations is attributed to the formation of larger oxidized Pt clusters and the aggregation of highly dispersed Pt species. The influence of the Pt surface noble metal concentration on the reaction rate is temporarily diminished when Pt particle formation is forced.

Interconversion of Atomically Dispersed Platinum Cations and Platinum Clusters in Zeolite ZSM-5 and Formation of Platinum gem-Dicarbonyls

Noah Felvey et al.

Summary: This study investigates the structure and properties of cationic platinum species in zeolite ZSM-5 through experimental and theoretical research. The results show that platinum clusters undergo oxidative fragmentation and form Pt2+ ions, which are stabilized in six-membered rings containing paired aluminum sites. These Pt2+ ions form uniform platinum gem-dicarbonyls in the presence of CO, which can be converted to Pt delta+ monocarbonyls in H-2. The conversion weakens the platinum-zeolite bonding and serves as the first step towards platinum migration and aggregation into clusters.

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.

Influence of ion mobility on the redox and catalytic properties of Cu ions in zeolites

Matteo Signorile et al.

Summary: This paper analyzes the influence of Al distribution, zeolite topology, ligands/reagents, and oxidation state on ions mobility in Cu-zeolites, and its impact on the reactivity of metal sites. The mobility of Cu ions has been observed in the presence of ammonia, enabling the activation of oxygen and providing a new perspective on the chemistry of zeolite-based catalysts. The different mobility of Cu+/Cu2+ ions, even in the absence of ligands, has important implications for the formation of Cu-oxo species and their activity in relevant reactions.

Summary: Metal-based heterogeneous catalysts are typically composed of supported nanoparticles a few nanometers in size, balancing active surface area with structural stability. These catalysts constantly evolve under reaction conditions, experiencing phenomena such as morphological changes, compound formation, segregation, leaching, and other interaction effects with the support material. Single-atom catalysts, particularly sensitive to their chemical environment, have also emerged as a new area of study in catalysis research.

Summary: This contribution reviews the structural features of supported bimetallic catalysts using IR spectroscopy of CO adsorption, focusing on active metals such as Au, Pd, Pt and Co. The difficulty in interpreting IR spectra during CO adsorption over certain bimetallic catalysts is highlighted, while crucial aspects like metal dispersion and surface segregation can still be obtained. The use of IR spectroscopy in investigating bimetallics or alloys remains challenging due to the complexity of spectra obtained, which depend on various parameters.

Dynamic restructuring of supported metal nanoparticles and its implications for structure insensitive catalysis

Charlotte Vogt et al.

Summary: In this study, structure insensitivity in catalysis was found to be linked to reaction-dependent particle size dependent restructuring. We observed particle size-dependent effects such as restructuring during ethene hydrogenation, which increased with increasing particle size, while no such effects were observed during CO2 hydrogenation. Additionally, we demonstrated that the rate of carbon diffusion on and into nanoparticles increases with particle size.
