Support-Dependent Cu-In Bimetallic Catalysts for Tailoring the Activity of Reverse Water Gas Shift Reaction
Thi Ha My Pham, Wen Luo, Kun Zhao, Mo Li, Youngdon Ko, Liping Zhong
Cu-based bimetallic catalysts have attracted great attention for the reverse water gas shift (RWGS) reaction due to their high activity and selectivity. This work reports the application of Cu-In bimetallic catalysts for the RWGS reaction and demonstrates ...
AMER CHEMICAL SOC2022Hydrogen Storage by Reduction of CO2 to Synthetic Hydrocarbons
Noris André Gallandat, Wen Luo, Jie Zhang, Kun Zhao
The storage of renewable energy is crucial for the substitution of fossil fuels with renewable energy. Hydrogen is the first step in the conversion of electricity from renewable sources to an energy carrier. However, hydrogen is technically and economicall ...
SWISS CHEMICAL SOC2021Monocarborane cluster as a stable fluorine-free calcium battery electrolyte
High-energy-density and low-cost calcium (Ca) batteries have been proposed as 'beyond-Li-ion' electrochemical energy storage devices. However, they have seen limited progress due to challenges associated with developing electrolytes showing reductive/oxida ...
NATURE PORTFOLIO2021CO2 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 ...
2020Mechanisms of the Heterogeneously Catalyzed Reaction of CO2 Hydrogenation on Transition Metal Surfaces
Renewable energy supply and energy storage in a closed materials cycle are the urgent global challenges of the 21st century. Carbon dioxide (CO2) hydrogenation over catalysts is a method to produce synthetic fuels from renewable energy in a CO2 neutral cyc ...
EPFL2020Thermal stability of size-selected copper nanoparticles: Effect of size, support and CO2 hydrogenation atmosphere
Andreas Züttel, Wen Luo, Mostapha Dakhchoune, Kun Zhao, Mo Li, Alexandre Borsay
Metal nanoparticles with a precisely controlled particle size distribution are ideal model catalysts for fundamental studies in catalysis. In this work, the thermal stability of size-selected Cu nanoparticles (Cu NPs) were deposited by magnetron sputtering ...
2020Imaging Catalysis: Operando Investigation of the CO2 Hydrogenation Reaction Dynamics by Means of Infrared Thermography
Andreas Züttel, Emad Oveisi, Emanuele Moioli, Kun Zhao, Robin Tobias Andreas Mutschler
Infrared thermography is a powerful tool to investigate the dynamic evolution of temperature in chemical reactions. The CO2 hydrogenation reaction is an ideal model reaction to assess the presented technique due to its high exothermicity. Various dynamic e ...
AMER CHEMICAL SOC2020Unraveling and optimizing the metal-metal oxide synergistic effect in a highly active Co (CoO)1– catalyst for CO2 hydrogenation
Andreas Züttel, Emanuele Moioli, Marco Calizzi, Loris Giovanni Lombardo, Wen Luo, Kun Zhao, Mo Li, Robin Tobias Andreas Mutschler, Alexandre Borsay
The relation between catalytic reactivities and metal/metal oxide ratios, as well as the functions of the metal and the metal oxides were investigated in the CO2 hydrogenation reaction over highly active Cox(CoO)1–x catalysts in operando. The catalytic rea ...
2020Electrochemical 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 ...
2020Solvent- and Catalyst-Free Carbon Dioxide Capture and Reduction to Formate with Borohydride Ionic Liquid
Paul Joseph Dyson, Kun Zhao, Heena Yang
The Cover Feature shows the application of a pyrrolidinium-based ionic liquid with a borohydride anion to simultaneously capture and reduce large amounts of CO2. The ionic liquid cation interacts with CO2, allowing the borohydride to fix and reduce it to t ...
