Membrane electrode assembly simulation of anion exchange membrane water electrolysis
Jan Van Herle, Suhas Nuggehalli Sampathkumar, Khaled Lawand, Zoé Mury
Anion exchange membrane water electrolysis (AEMWE) offers a green hydrogen production method that eliminates the need for platinum group metals (PGM) as electrocatalysts. This study employs a COMSOL (R) 6.0 model to simulate a 1x1 cm(2) Ni fibre - Raney (R ...
Amsterdam2024Anisotropic In-Plane strain engineering Ni(OH)2 to activate alkaline hydrogen evolution reaction
Realizing a hydrogen economy strongly requires alkaline water electrolysis to achieve large-scale generation of H2, but lacks stable and efficient catalysts. The insufficient active sites in Ni(OH)2 impair the catalytic performance of alkaline HER. Herein, ...
ELSEVIER SCIENCE SA2023Assessing the effect of O2 dithering on CH4 oxidation on Pd/Al2O3
Under periodic lean/rich operation generated by repeated O2 pulses (O2-dithering), the abatement of CH4 and NO is enhanced compared to static operation. However, it is not well understood how the dithering parameters (pulse amplitude and frequency) affect ...
ELSEVIER SCIENCE SA2023The spatial distribution of cobalt phthalocyanine and copper nanocubes controls the selectivity towards C-2 products in tandem electrocatalytic CO2 reduction
Raffaella Buonsanti, Anna Loiudice, Min Wang, Valery Okatenko
The coupling of CO-generating molecular catalysts with copper electrodes in tandem schemes is a promising strategy to boost the formation of multi-carbon products in the electrocatalytic reduction of CO2. While the spatial distribution of the two component ...
ROYAL SOC CHEMISTRY2023Monitoring and understanding Cu catalyst dissolution during CO2 electroreduction
Electrochemical reduction of carbon dioxide is a promising approach to decrease the amount of anthropogenic CO2 being released into the atmosphere, provided that a surplus of renewable electrical energy is available. Copper based materials are at the cente ...
EPFL2022Adsorption Behavior of the Coenzyme NADH at the Carbon/ Electrolyte Interface Determined by Neutron Reflectometry
The adsorption behavior of beta-nicotinamide adenine dinucleotide (NADH) at the carbon/electrolyte interface has been studied using a combination of neutron reflectometry (NR) and solution depletion isotherms. Coupling the NR technique with an electrochemi ...
2022Hydro-processing of biomass using novel metal-organic framework (MOF)/polymer composite catalysts
Generating value, in the form of functional chemicals, from biomass is a critical need of today. It is expected that replacing petroleum with biomass as the source of many commodity and fine chemicals can lead the transition away from a fossil-fuel based e ...
EPFL2022Construction of Functional Superhydrophobic Biochars as Hydrogen Transfer Catalysts for Dehydrogenation of N-Heterocycles
To endow metal-free materials with the high catalytic activity that is typically featured by a metal-based catalyst is yet a constant pursuit in the field of catalytic chemistry. In this work, novel functional biochars (DCNs) were prepared from wheat straw ...
AMER CHEMICAL SOC2021Copper Nanocrystal Morphology Determines the Viability of Molecular Surface Functionalization in Tuning Electrocatalytic Behavior in CO2 Reduction
Raffaella Buonsanti, James Richard Pankhurst, Valery Okatenko, Pranit Srinivas Iyengar
Molecular surface functionalization of metallic catalysts is emerging as an ever-developing approach to tuning their catalytic performance. Here, we report the synthesis of hybrid catalysts comprising copper nanocrystals (CuNCs) and an imidazolium ligand f ...
AMER CHEMICAL SOC2021Continuous hydrogenolysis of acetal-stabilized lignin in flow
Jeremy Luterbacher, Songlan Sun, Jean Thierry C Behaghel de Bueren, Florent Emmanuel Héroguel, Yuan-Peng Du, Wu Lan
Using acetal-stabilized lignin we performed a truly steady state continuous high-yielding lignin depolymerization (45% monophenolics using Ni/C), which offered a window into challenges and opportunities that will be faced when processing this feedstock. Wi ...
