The Impact of Surfactants on the Inertial Separation of Bubbles in Microfluidic Electrolyzers

Improving the throughput of electrochemical reactions such as water electrolysis is an ongoing effort. In a membrane-less electrolyzer, product separation can be achieved via controlled two-phase flows within the electrochemical flow cells. In this case, i ...

Discrete Helmholtz charge distribution at liquid-liquid interfaces: Electrocapillarity, capacitance and non-linear spectroscopy studies

Hubert Girault, Grégoire Clément Gschwend

The structure of the polarised interface between two immiscible electrolyte solutions (ITIES) has usually been deduced from electrocapillarity and capacitance measurements. However, these two methods only offer an indirect access to the surface change dens ...

Coupled As and Mn Redox Transformations in an Fe(0) Electrocoagulation System: Competition for Reactive Oxidants and Sorption Sites

Sachiko Hirosue, Jasquelin Peña, Nathalie Manetti

Iron electrocoagulation (EC) can be used for the decentralized treatment of arsenic(As)-contaminated groundwater. Iron EC involves the electrolytic dissolution of an Fe(0) electrode to Fe(II). This process produces reactive oxidants, which oxidize As(III) ...

Power-to-methane via co-electrolysis of H2O and CO2: The effects of pressurized operation and internal methanation

François Maréchal, Jan Van Herle, Stefan Diethelm, Ligang Wang, Tzu-En Lin, Hanfei Zhang

This paper presents a model-based investigation to handle the fundamental issues for the design of co-electrolysis based power-to-methane at the levels of both the stack and system: the role of CO2 in co-electrolysis, the benefits of employing pressurized ...

Power-to-fuels via solid-oxide electrolyzer: Operating window and techno-economics

François Maréchal, Jan Van Herle, Stefan Diethelm, Ligang Wang, Tzu-En Lin

Power-to-fuel systems via solid-oxide electrolysis are promising for storing excess renewable electricity by efficient electrolysis of steam (or co-electrolysis of steam and CO2) into hydrogen (or syngas), which can be further converted into synthetic fuel ...

Techno-Economic Optimization of CO2-to-Methanol with Solid-Oxide Electrolyzer

François Maréchal, Jan Van Herle, Ligang Wang, Hanfei Zhang

Carbon capture and utilization are promising to tackle fossil-fuel depletion and climate change. CO2 hydrogenation can synthesize various chemicals and fuels, such as methanol, formic acid, urea, and methane. CO2-to-methanol integrated with solid-oxide ele ...
