Mechanism of Cobalt-Manganese Catalysts Deciphered

Combination of different methods was the key to success

22-Oct-2024 - The energy carrier hydrogen can be obtained from water by electrolysis. This works particularly well with Cobalt spinel electrocatalysts containing manganese. However, it was unclear why. Conventional catalysts for hydrogen production via water electrolysis usually contain precious metals and are ...

Increasing the Activity of Catalysts

A key to producing green hydrogen more efficiently

13-Jan-2021 - A layer as thin as a single atom makes a huge difference: On the surface of an electrode, it doubles the amount of water split in an electrolysis system without increasing the energy requirements. Thus, the ultrathin layer also doubles the amount of hydrogen produced without increasing costs. ...

More efficient and cheaper synthetic fuels with 3D printing

26-Sep-2018 - Co-electrolysis is a new and very efficient way of producing synthetic fuels and chemicals from CO2 and water. Diesel and petrol cars as well as trucks, airplanes, and ships could run on such fuels in a climate neutral manner. They can also be used as energy storage systems, which could help ...

Researchers develop catalyst material for fuel cells

Platinum-nickel nano-octahedra save 90 % platinum

19-Jun-2013 - Efficient, robust and economic catalyst materials hold the key to achieving a breakthrough in fuel cell technology. Scientists from Jülich and Berlin have developed a material for converting hydrogen and oxygen to water using a tenth of the typical amount of platinum that was previously required. ...
