Noble Metal Nanoparticles Stabilized by Hyper-Cross-Linked Polystyrene as Effective Catalysts in Hydrogenation of Arenes
This work is addressing the arenes' hydrogenation-the processes of high importance for petrochemical, chemical and pharmaceutical industries. Noble metal (Pd, Pt, Ru) nanoparticles (NPs) stabilized in hyper-cross-linked polystyrene (HPS) were shown to be a ...
2021Fe-57-Enrichment effect on the composition and performance of Fe-based O-2-reduction electrocatalysts
Jeremy Luterbacher, Benjamin Pierre Le Monnier
Pt-group metal (PGM)-free catalysts of the Me-N-C type based on abundant and inexpensive elements have gained importance in the field of oxygen reduction reaction (ORR) electrocatalysis due to their promising ORR-activities. Their insufficient stability, h ...
ROYAL SOC CHEMISTRY2021Silica-copper catalyst interfaces enable carbon-carbon coupling towards ethylene electrosynthesis
Michael Graetzel, Dan Ren, Yelin Hu, Jun Li, Reza Zamani, Xiaoyan Wang, Ziyun Wang, Yi Xu
Membrane electrode assembly (MEA) electrolyzers offer a means to scale up CO2-to-ethylene electroconversion using renewable electricity and close the anthropogenic carbon cycle. To date, excessive CO2 coverage at the catalyst surface with limited active si ...
NATURE RESEARCH2021Shaping Copper Nanocatalysts to Steer Selectivity in the Electrochemical CO2 Reduction Reaction
Raffaella Buonsanti, Kevin Rossi
The carbon-neutral production of fuels and chemical feedstocks is one of the grand challenges for our society to solve. The electrochemical conversion of CO2 is emerging as a promising technology contributing to this goal. Despite the huge amount of progre ...
2021Data-Driven Advancement of Homogeneous Nickel Catalyst Activity for Aryl Ether Cleavage
Matthew Wodrich, Benjamin André René Meyer, Manuel Cordova, Boodsarin Sawatlon
The increasing urgency to make chemical processes more environmentally friendly while continuing to derive the chemicals required for modern society from renewable resources requires the development of a forthcoming generation of synthetic processes and th ...
AMER CHEMICAL SOC2020Insights into the Photocatalytic Bacterial Inactivation by Flower-Like Bi2WO6 under Solar or Visible Light, Through in Situ Monitoring and Determination of Reactive Oxygen Species (ROS)
César Pulgarin, Juan Kiwi, Sami Rtimi, Stefanos Giannakis, Minoo Karbasi
This study addresses the visible light-induced bacterial inactivation kinetics over a Bi2WO6 synthesized catalyst. The systematic investigation was undertaken with Bi2WO6 prepared by the complexation of Bi with acetic acid (carboxylate) leading to a flower ...
2020Unraveling the synergy between metal-organic frameworks and co-catalysts in photocatalytic water splitting
Alfredo Pasquarello, Stefano Falletta, Kyriakos Stylianou, Stavroula Kampouri, Patrick Gono, Zhendong Guo
We investigate the synergy occurring in photocatalytic water splitting between the metal-organic framework MIL-125-NH(2)and two co-catalysts, namely NiO and Ni2P, by calculating their band edge alignment with respect to the redox levels of liquid water. Fo ...
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 ...
EPFL2020Near-Enantiopure Trimerization of 9-Ethynylphenanthrene on a Chiral Metal Surface
Harald Brune, Roland Widmer, Aliaksandr Yakutovich, Jan Prinz, Samuel Thomas Stolz
Enantioselectivity in heterogeneous catalysis strongly depends on the chirality transfer between catalyst surface and all reactants, intermediates, and the product along the reaction pathway. Herein we report the first enantioselective on-surface synthesis ...
2020Activation of small molecules promoted by multimetallic complexes supported by redox active ligands
The activation of small molecule is a topic of high current interest. A variety of homogeneous end heterogeneous catalysts have been studied to be able to promote chemical transformation of industrial relevance under mild condition and therefore decrease t ...
