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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

We demonstrate the ability of tetraalkylammonium borohydrides to capture large amounts of CO2, even at low CO2 concentrations, and reduce it to formate under ambient conditions. These materials show CO2 absorption capacities up to 30 mmolCO2 g(-1) at room ...

Cu-catalyzed electrochemical CO2 reduction reaction (CO2RR) to multi-carbon (C2+) products is often plagued by low selectivity because the adsorption energies of different reaction intermediates are in a linear scaling relationship. Development of Cu-based ...

CO2 hydrogenation over catalysts is a potentially exciting method to produce fuels while closing the CO2 cycle and mitigating global warming. The mechanism of this process has been controversial due to the difficulty in clearly identifying the species pres ...

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 ...

The electrochemical reduction of CO2 to higher hydrocarbons is a very challenging process that has high potential for the storage of large amounts of renewable energy with a high gravimetric and volumetric energy density. The distribution of hydrocarbons f ...

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 ...

Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) investigations of molecules at the surface of catalysts exhibit a strong overlap of the adsorption peaks. Therefore, the investigation of the CO2 hydrogenation on a highly active catalyst ...

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 ...
