Heterogeneous catalyst preparation by liquid-phase atomic layer deposition

Heterogeneous catalyst preparation has been performed for close to a century but has been rapidly evolving spurred by the evolution in synthetic techniques and growing needs in energy, chemicals and materials. An increasing number of catalyst synthesis str ...

Fe-57-Enrichment effect on the composition and performance of Fe-based O-2-reduction electrocatalysts

Jeremy Luterbacher, Benjamin Pierre Le Monnier

Pt-group metal (PGM)-free catalysts of the Me-N-C type based on abundant and inexpensive elements have gained importance in the field of oxygen reduction reaction (ORR) electrocatalysis due to their promising ORR-activities. Their insufficient stability, h ...

Catalyst Evolution Enhances Production of Xylitol from Acetal-Stabilized Xylose

Jeremy Luterbacher, Benjamin Pierre Le Monnier, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Jher Hau Yeap

We demonstrate a catalytic process for xylitol production based on the volatility and unique reactivity of diformylxylose (DFX), which can be produced at near theoretical yield from biomass and, contrary to xylose, can be easily purified by distillation. T ...

Catalytic valorization of the acetate fraction of biomass to aromatics and its integration into the carboxylate platform

Jeremy Luterbacher, Benjamin Pierre Le Monnier, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Jher Hau Yeap, Bartosz Rozmyslowicz

In many plant species, the acetate fraction is the fourth most prominent fraction by weight after cellulose, hemicellulose and lignin, and can be easily extracted as a single stable molecule, acetic acid, at high yields. Despite this, upgrading the acetate ...

Catalyst stabilization by stoichiometrically limited layer-by-layer overcoating in liquid media

Jeremy Luterbacher, Florent Emmanuel Héroguel, Benjamin Pierre Le Monnier

The use of metal oxide overcoats over supported nanoparticle catalysts has recently led to impressive improvements in catalyst stability and selectivity. The deposition of alumina is especially important for renewable catalysis due to its robustness in liq ...

Simulation of Gas- and Liquid-Phase Layer-By-Layer Deposition of Metal Oxides by Coarse-Grained Modeling

Jeremy Luterbacher, Florent Emmanuel Héroguel, Benjamin Pierre Le Monnier

Atomic layer deposition (ALD) and chemical layer deposition (CLD) are techniques to produce conformal, atomically precise overcoats for materials in gas and liquid phases, respectively. Although it is a challenge to explicitly model ALD/CLD dynamics becaus ...

Atomic Layer Deposition on Dispersed Materials in Liquid Phase by Stoichiometrically Limited Injections

Frederick Georges Wells, Jeremy Luterbacher, Benjamin Pierre Le Monnier, Farzaneh Talebkeikhah

Atomic layer deposition (ALD) is a well‐established vapor‐phase technique for depositing thin films with high conformality and atomically precise control over thickness. Its industrial development has been largely confined to wafers and low‐surface‐area ma ...

Clean, cleaved surfaces of the photovoltaic perovskite

László Forró, Henrik Moodysson Rønnow, Jeremy Luterbacher, Bálint Náfrádi, Endre Horvath, Jan Hugo Dil, Stefan Peter Muff, Andrew Patton Weber, Márton Kollár, Luka Ciric, Benjamin Pierre Le Monnier

The surface of a material is not only a window into its bulk physical properties, but also hosts unique phenomena important for understanding the properties of a solid as a whole. Surface sensitive techniques, like ARPES (Angle-resolved photoemission spect ...

Increasing the activity of the Cu/CuAl2O4/Al2O3 catalyst for the RWGS through preserving the Cu2+ ions

Jeremy Luterbacher, Oliver Kröcher, Florent Emmanuel Héroguel, Alimohammad Bahmanpour, Yuan-Peng Du, Benjamin Pierre Le Monnier

Cu-Al spinet oxide is a highly active catalyst for CO2 conversion to CO. However, it suffers from low surface area. By depositing a silica layer, we protected the catalyst surface and preserved the Cu2+ ions during the calcination process. These ions form ...

Atom-by-Atom Synthesis of Multiatom-Supported Catalytic Clusters by Liquid-Phase Atomic Layer Deposition

Ursula Röthlisberger, Jeremy Luterbacher, Mounir Driss Mensi, Claudia Esther Avalos, Benjamin Pierre Le Monnier, Murat Kiliç, Louisa Marie Savereide

Here, we introduce a method for the synthesis of atomically precise, supported, multiatom catalysts by liquid-phase atomic layer deposition. This technique is based on consecutive grafting reactions in mild conditions that build supported active sites atom ...
