Atomic Level Insights of Non-Noble Metal Catalysts for the Oxygen Evolution Reaction

Lichen Bai

The conversion of intermittent renewable energy resources in the form of chemical bond, such as hydrogen production from electrochemical water splitting, is a promising way to satisfy the future global energy demand and address the environmental issues. Th ...

Controllable CO adsorption determines ethylene and methane productions from CO2 electroreduction

Yang Li, Jun Li, Zhiwen Zhou, Hao Yang, Bo Zhang

Among all CO2 electroreduction products, methane (CH4) and ethylene (C2H4) are two typical and valuable hydrocarbon products which are formed in two different pathways: hydrogenation and dimerization reactions of the same CO intermediate. Theoretical studi ...

Continuous hydrogenolysis of acetal-stabilized lignin in flow

Jeremy Luterbacher, Songlan Sun, Jean Thierry C Behaghel de Bueren, Florent Emmanuel Héroguel, Yuan-Peng Du, Wu Lan

Using acetal-stabilized lignin we performed a truly steady state continuous high-yielding lignin depolymerization (45% monophenolics using Ni/C), which offered a window into challenges and opportunities that will be faced when processing this feedstock. Wi ...

Mechanisms of the Heterogeneously Catalyzed Reaction of CO2 Hydrogenation on Transition Metal Surfaces

Kun Zhao

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 ...

EPFL2020

Water splitting offers the opportunity for storing solar energy and, thus, producing carbon-neutral and renewable solar fuels. The process, known as artificial photosynthesis, is limited by the electrocatalytic conversion of water into molecular oxygen. El ...

Biomimetic Hydrogenation Catalyzed by a Manganese Model of [Fe]-Hydrogenase

Xile Hu, Huijie Pan

[Fe]‐hydrogenase is an efficient biological hydrogenation catalyst. Despite intense research, Fe complexes mimicking the active site of [Fe]‐hydrogenase have not achieved turnovers in hydrogenation reactions. Herein, we describe the design and development ...
