How catalysts secretly lose their stability

Covalent organic framework compounds are more active as catalysts than one would expect

28-Nov-2024 - Covalent organic frameworks (COFs) are less stable as catalysts than previously thought but remain highly active. COFs are promising designer catalysts, for example for the sustainable production of chemicals and fuels. Their properties can be adjusted very specifically to catalyze a desired ...

Maximizing Hydrogen Peroxide Formation during Water Electrolysis

Killing two birds with one stone

23-Jul-2024 - When water is split electrolytically, the result is typically hydrogen – and useless oxygen. Instead of oxygen, you can also produce a useful product. If you know how. Due to its high availability, water is considered the most useful starting material for hydrogen production. Ideally, the ...

Wastewater treatment plants as drivers for the energy transition

Technical add-on module can, in principle, turn any wastewater treatment plant into a CO2 sink and decentralized methane production plant

21-Sep-2023 - By implementing an innovative technology, any wastewater treatment plant would be able to produce methane from carbon dioxide in an environmentally friendly way. If some microorganisms present in wastewater treatment plants are additionally supplied with hydrogen and carbon dioxide, they produce ...

Protecting biocatalysts from oxygen

A genetic modification can make hydrogen-producing enzymes more stable

13-Jan-2023 - Certain enzymes from bacteria and algae can produce molecular hydrogen from protons and electrons – an energy carrier on which many hopes are riding. All they need for this purpose is light energy. The major obstacle to their use is that they are destroyed by contact with oxygen. An ...

Unexpected energy storage capability where water meets metal surfaces

Capacitively stored charge at platinum interfaces can be significantly higher than previously assumed

20-Jan-2022 - A new method can measure the electrical (re-)charging of boundary layers between very small, metallic particles and aqueous solutions and understand it at a molecular level. Researchers from the RESOLV Cluster of Excellence at Ruhr-Universität Bochum (RUB) have used current and voltage ...
