Developing soft X-ray spectroscopy for in situ characterization of nanocatalysts in catalytic reactions

The mechanisms of catalytic and reactions can be investigated by in situ and operando spectroscopy. We report the developments of an in situ reaction cells for soft X-ray spectroscopy of nanoparticle catalysts.. The operation of the cells and their capabilities are illustrated with examples from the studies of Co-based nanocatalysts.

Organometallic Ruthenium Nanoparticles as Model Catalysts for CO Hydrogenation: A Nuclear Magnetic Resonance and Ambient-Pressure X-ray Photoelectron Spectroscopy Study

We present a study of the structure and reactivity of Ru nanoparticles of different sizes for CO hydrogenation using gas phase NMR and mass spectroscopy. In addition the nanoparticles were characterized under reaction mixtures in situ by ambient-pressure X-ray photoelectron spectroscopy. We found that during reaction the Ru is in the metallic state and that the diphosphine ligands (dppb) on the surface of nanoparticles of 1.9 and 3.1 nm, act not only as capping and protecting agents, but stay on the surface during reaction and improve their activity and selectivity towards C2-C4 hydrocarbons.

Carbon monoxide-induced dynamic metal-surface nanostructuring

Carbon monoxide is a ubiquitous molecule in surface science, materials chemistry, catalysis and nanotechnology. Its interaction with a number of metal surfaces is at the heart of major processes, such as Fischer-Tropsch synthesis or fuel-cell optimization. Recent works have highlighted the ability of metal surfaces and nanoparticles to undergo restructuring after exposure to CO under fairly mild conditions, generating nanostructures. This Minireview deals with such nanostructuring, and discusses the driving force in reversible and non-reversible situations.

Exploring nanoscaled matter from speciation to phase diagrams: metal phosphide nanoparticles as a case of study

This critical review deals with the question of nanoscale phase diagram. Because of their high surface-to-volume ratio, nanoparticles sometimes show phase preferences for certain composition, or even display phase segregation phenomena that one would not expect at the bulk scale. Here, we took metal phosphides as a case study to discuss this exiting side of nanoscale matter.
