Revisiting the Impact of Morphology and Oxidation State of Cu on CO2 Reduction Using Electrochemical Flow Cell

Shaik Mohammed Zakeeruddin, Jing Gao, Dan Ren

Electroreduction of carbon dioxide (CO2) in a flow electrolyzer represents a promising carbon-neutral technology with efficient production of valuable chemicals. In this work, the catalytic performance of polycrystalline copper (Cu), Cu2O-derived copper (O ...

Tandem effect of Ag@C@Cu catalysts enhances ethanol selectivity for electrochemical CO2 reduction in flow reactors

Andreas Züttel, Thi Ha My Pham, Cedric David Koolen, Wen Luo, Jie Zhang, Mo Li, Youngdon Ko, Liping Zhong

CO-selective metals (e.g., Ag) on Cu catalysts improve the selec-tivity of multi-carbon (C2+) products in electrochemical CO2 reduc-tion. However, the origin of the improvement remains unclear due to the convolution of tandem and interface effects. Here, A ...

Crossover of liquid products from electrochemical CO2 reduction through gas diffusion electrode and anion exchange membrane

Andreas Züttel, Wen Luo, Jie Zhang

We reveal that a significant amount (>30%) of the liquid products from electrochemical CO2 reduction (CO2RR) in a flow reactor can cross the gas diffusion electrode (GDE) and anion exchange membrane (AEM). Crossover of volatile products through the GDE occ ...

Electrochemical reconstruction of ZnO for selective reduction of CO2 to CO

Andreas Züttel, Emanuele Moioli, Wen Luo, Jie Zhang, Kun Zhao, Qin Zhang

Electrocatalytic conversion of CO2 to valuable chemicals is a highly promising route to close the carbon cycle. Herein, Zn catalysts derived from electrochemical reconstruction of ZnO materials are presented as efficient CO2-to-CO catalysts. We found that ...

Reversible solid-oxide cell stack based power-to-x-to-power systems: Comparison of thermodynamic performance

François Maréchal, Jan Van Herle, Ligang Wang, Philippe Aubin, Tzu-En Lin, Maria del Mar Perez Fortes, Yumeng Zhang

The increasing penetration of variable renewable energies poses new challenges for grid management. The economic feasibility of grid-balancing plants may be limited by low annual operating hours if they work either only for power generation or only for pow ...

On isothermality in some commonly used plug flow reactors for X-ray based investigations of catalysts

Dragos-Constantin Stoian, Mark Adrian Newton

We compare two reactor setups commonly used to make operando measurements of catalyst behavior using X-rays in terms of the degree to which they may be considered to yield radial and axial isothermality. We use axial and radial Cu K-edge XANES mapping of c ...

Nondiffusive transport regimes for suprathermal ions in turbulent plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

The understanding of the transport of suprathermal ions in the presence of turbulence is important for fusion plasmas in the burning regime that will characterize reactors, and for space plasmas to understand the physics of particle acceleration. Here, thr ...

Non-stationarity in experimental travel time measured in a lysimeter: theoretical and modeling lessons from a simplified hydrological system

Andrea Rinaldo, Enrico Bertuzzo, Pierre Claude Jean Queloz, Luca Carraro, Gianluca Botter

Experimental data have been collected over a year-long period in a large weighing lysimeter. Natural climatic forcing occurs, except for rainfall which is artificially generated as a given Poisson process at a daily timescale. A constant water table is mai ...

Modelling bacterial selection during the plug-flow feeding phase of aerobic granular sludge biofilm reactors

Christof Holliger, David Gregory Weissbrodt

A mathematical model was developed to investigate hydraulic transport and bacterial selection during slow up-flow anaerobic feeding (0.9 m h-1) of wastewater across the settled bed of granular sludge biofilms used in column-type sequencing-batch reactors t ...
