Co-Adsorption of Alcohols and Water in JUK-8 Studied Using Quasi-Equilibrated Thermodesorption
JUK-8 ([Zn(oba)(pip)]n, oba2- = 4,4 '-oxybis(benzenedicarboxylate), pip = 4-pyridyl-functionalized benzene-1,3-dicarbohydrazide) is a hydrolytically stable flexible metal-organic framework. Owing to its unusual adsorptive properties, JUK-8 can be considere ...
MDPI2024In Situ Monitoring of the Surface Evolution of a Silver Electrode from Polycrystalline to Well-Defined Structures
Capturing the surface-structural dynamics of metal electrocatalysts under certain electrochemical environments is intriguingly desired for understanding the behavior of various metal-based electrocatalysts. However, in situ monitoring of the evolution of a ...
AMER CHEMICAL SOC2022Realistic Modelling of Dynamics at Nanostructured Interfaces Relevant to Heterogeneous Catalysis
The focus of this short review is directed towards investigations of the dynamics of nanostructured metallic heterogeneous catalysts and the evolution of interfaces during reaction-namely, the metal-gas, metal-liquid, and metal-support interfaces. Indeed, ...
MDPI2022Born to be different: the formation process of Cu nanoparticles tunes the size trend of the activity for CO2 to CH4 conversion
We investigate the impact of the formation process of Cu nanoparticles on the distribution of adsorption sites and hence on their activity. Using molecular dynamics, we model formation pathways characteristic of physical synthesis routes as the annealing o ...
ROYAL SOC CHEMISTRY2021Colloidal-ALD Grown Hybrid Shells Nucleate via a Ligand–Precursor Complex
David Lyndon Emsley, Raffaella Buonsanti, Anna Loiudice, Michael Allan Hope, Ona Segura Lecina, Kevin Rossi, Snaedis Björgvinsdóttir, Amrit Venkatesh
Colloidal atomic layer deposition (c-ALD) enables the growth of hybrid organic/inorganic oxide shells with tunable thickness at the nanometer scale around ligand-functionalized inorganic nanoparticles (NPs). This recently developed method has demonstrated ...
2021CO2 chemical transformations using metal-organic frameworks
During the last decades, intensive efforts have been applied to tackle the enormous emissions of CO2 into atmosphere. These efforts include not only developing efficient carbon capture techniques, but also the introduction of new ways to transform the capt ...
EPFL2020Synthesis of heterogeneous catalysts with metal oxide overcoat for renewable catalysis applications
Metal oxide deposition is an emerging synthetic technique for designing heterogeneous catalysts. Depositing a nanoscale overcoat of metal oxide on heterogeneous catalysts can modify their structural and chemical characteristics. Many deposition approaches, ...
EPFL2020New Approach to Synthesis of Tetralin via Naphthalene Hydrogenation in Supercritical Conditions Using Polymer-Stabilized Pt Nanoparticles
Supercritical (SC) fluid technologies are well-established methods in modern green chemical synthesis. Using SC fluids as solvents instead of traditional liquids gives benefits of higher diffusivity and lower viscosity, which allows mass transfer intensifi ...
2020Dynamics of nanoscale systems probed by time-resolved STM-induced luminescence
The efficiency and peculiarities of processes such as surface adsorption or electron-to-photon energy conversion in organic and inorganic structures are determined by the dynamics at the scale of individual molecules, atoms and charges. The timescales of s ...
EPFL2019Molecular tunability of surface-functionalized metal nanocrystals for selective electrochemical CO2 reduction
Raffaella Buonsanti, Mounir Driss Mensi, James Richard Pankhurst, Yannick Thomas Guntern
Organic ligands are used in homogeneous catalysis to tune the metal center reactivity; in contrast, clean surfaces are usually preferred in heterogeneous catalysis. Herein, we demonstrate the potential of a molecular chemistry approach to develop efficient ...
