Golden Ball Mills as Green Catalysts

A gold-coated grinding bowl proves to be a real marvel

18-Jun-2024 - Less waste, mild reaction conditions, and no harmful solvents – only a very thin layer of gold is necessary to sustainably convert alcohols into aldehydes through mechanochemistry. A gold-coated milling vessel for ball mills proved to be a real marvel in the research work by Inorganic Chemistry ...

Light and milling balls for greener chemical processes

Reactions without solvents

16-Mar-2023 - A combination of photochemistry and mechanochemistry saves 98 per cent solvent and 80 per cent energy in a number of reactions. What’s more, the process takes less time than it does in solution. Light-driven chemical reactions so far were usually conducted with large amounts of solvents that are ...

How light activates MoS2 layers to become catalysts

08-Mar-2021 - Thin films of molybdenum and sulfur belong to a class of materials that can be considered for use as photocatalysts. Inexpensive catalysts such as these are needed to produce hydrogen as a fuel using solar energy. However, they are still not very efficient as catalysts. A new instrument at the ...

Nanoceramics from the ball mill

Nanometer-sized corundum particles can now be produced amazingly easily

01-Nov-2019 - Automotive catalysts, among others, and materials for dental implants could become more robust and easier to manufacture than ever before. This is because chemists at the Max-Planck-Institut für Kohlenforschung in Mülheim an der Ruhr have found a way to produce corundum (also known as ...
