Hydrogen production on demand by redox-mediated electrocatalysis: A kinetic study
Hubert Girault, Sunny Isaïe Maye, Danick Reynard
Producing hydrogen from water using a redox mediator on solid electrocatalyst particles in a reactor offers several advantages over classical electrolysis in terms of safety, membrane degradation, purity and flexibility. Herein, vanadium-mediated hydrogen ...
ELSEVIER SCIENCE SA2021Micro-Electrode with Fast Mass Transport for Enhancing Selectivity of Carbonaceous Products in Electrochemical CO2 Reduction
Mingkui Wang, Jingshan Luo, Dan Ren, Xiaoyu Zhang, Qixing Zhang
During electrochemical carbon dioxide (CO2) reduction on copper electrodes in an aqueous electrolyte, one of the key challenges is the competition between hydrogen evolution and CO2 reduction, especially under large current density. Here, micro-electrodes ...
WILEY-V C H VERLAG GMBH2021Revealing the Surface Chemistry for CO2 Hydrogenation on Cu/CeO2–x Using Near-Ambient-Pressure X-ray Photoelectron Spectroscopy
Andreas Züttel, Emad Oveisi, Thi Ha My Pham, Wen Luo, Mo Li, Young Jun Ko
Catalytic reduction of CO2 to valuable products is an attractive route for CO2 recycling. CeO2-supported Cu catalysts have shown high activity and selectivity for the hydrogenation of CO2 to CO. To uncover the origin of their high performance, we prepared ...
ACS2021Practical challenges in the development of photoelectrochemical solar fuels production
Sophia Haussener, Miguel Antonio Modestino
This article addresses the challenges presented by photoelectrochemical solar fuels technology in a discussion that begins with a functioning device and proceeds to the more fundamental science of its component parts. In this flow of discussion issues are ...
2020CO2 Hydrogenation over Unsupported Fe-Co Nanoalloy Catalysts
Andreas Züttel, Marco Calizzi, Kun Zhao, Robin Tobias Andreas Mutschler, Nicola Patelli
The thermo-catalytic synthesis of hydrocarbons from CO2 and H2 is of great interest for the conversion of CO2 into valuable chemicals and fuels. In this work, we aim to contribute to the fundamental understanding of the effect of alloying on the reaction y ...
2020Mitigating the variability of hydrogen production in mixed culture through bioaugmentation with exogenous pure strains
Simon Marius Jean Poirier, Nicolas Bernet
Process stability is a key operational issue when operating dark fermentation with mixed microbial cultures for hydrogen production. This study aimed at mitigating the instability of hydrogen production by separately adding exogenous pure strains suspected ...
PERGAMON-ELSEVIER SCIENCE LTD2020Design of a Pilot SOFC System for the Combined Production of Hydrogen and Electricity under Refueling Station Requirements
François Maréchal, Jan Van Herle, Stefan Diethelm, Alberto Mian, Maria del Mar Perez Fortes
The objective of the current work is to support the design of a pilot hydrogen and electricity producing plant that uses natural gas (or biomethane) as raw material, as a transition option towards a 100% renewable transportation system. The plant, with a s ...
WILEY-V C H VERLAG GMBH2019Controlling strategies to maximize reliability of integrated photo-electrochemical devices exposed to realistic disturbances
Sophia Haussener, Saurabh Yuvraj Tembhurne
We numerically investigate the conversion of solar energy into chemical energy by integrated photo-electrochemical (IPEC) devices and assess their response to time-dependent changes in the boundary conditions and the material properties. We focus on a devi ...
RSC2019Heterogeneous Catalytic Reactor for Hydrogen Production from Formic Acid and Its Use in Polymer Electrolyte Fuel Cells
Gabor Laurenczy, Nordahl Autissier, Katerina Stefania Sordakis, Martin Grasemann, Andrew Francis Dalebrook
A proof-of-concept prototype of a medium-scale heterogeneous catalytic reactor for continuous production of hydrogen through formic acid (FA) dehydrogenation has been developed. A commercial proton exchange membrane (PEM) fuel cell (FC) fed with the result ...
2018Electrochemical Dynamics of a Single Platinum Nanoparticle Collision Event for the Hydrogen Evolution Reaction
Pekka Eero Peljo, Haiqiang Deng
Chronoamperometry was used to study the dynamics of Pt nanoparticle (NP) collision with an inert ultramicroelectrode via electrocatalytic amplification (ECA) towards hydrogen evolution reaction. First, ECA and dynamic light scattering (DLS) results reveal ...
