Unraveling 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 ...

Hydrogenation of ZnFe2O4 Flat Films: Effects of the Pre-Annealing Temperature on the Photoanodes Efficiency for Water Oxidation

Kevin Sivula, Charles Roger Jean Lhermitte, Annalisa Polo

The effects induced by post-synthesis hydrogenation on ZnFe2O4 flat films in terms of photoelectrochemical (PEC) performance of photoanodes for water oxidation have been deeply investigated as a function of the pre-annealing temperature of the materials. T ...

Solvent- 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 ...

Sustainable Hydrogenation of Nitroarenes to Anilines with Highly Active in-situ Generated Copper Nanoparticles

Berend Smit, Mounir Driss Mensi, Kyriakos Stylianou, Ngoc Tú Nguyên, Christopher Patrick Ireland, Fatma Pelin Uran

Metal nanoparticles (NPs) are usually stabilized by a capping agent, a surfactant, or a support material, to maintain their integrity. However, these strategies can impact their intrinsic catalytic activity. Here, we demonstrate that the in-situ formation ...

Mitigating 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 ...
