Wood-based catalyst to keep fruit fresh

If freshly bought bananas are stored in a full fruit basket, then they won't stay yellow very long. Just a few days later, the crooked fruits take on a brownish color and are more likely to be thrown away than be eaten. The ...

An 'exceptionally stable' single-atom catalyst

Scientists at Tokyo Institute of Technology (Tokyo Tech) have shown that single platinum atoms trapped in C12A7 crystals act as a stable and effective catalyst for the hydrogenation of nitroarenes, an essential process in ...

New catalyst outshines platinum for producing hydrogen

Hydrogen, the most abundant element in the universe, packs a powerful punch. And because it contains no carbon, it produces only water when used as a fuel. But on Earth, hydrogen most often exists in combination with other ...

Shocking heat waves stabilize single atoms

Single atoms work great as catalysts, but they usually don't stay single for long. Argonne scientists are part of a team that uses high-temperature shock waves to keep them in their place.

Activity of fuel cell catalysts doubled

An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as potent as the best process commercially ...
