A simplified schematic depicting the formation mechanism of NiPt nanocatalysts with a dome-shaped hollow polycrystalline structure incorporating a Ni3Pt5 intermetallic phase. The process is driven by ...

Thanks to a novel combination of cryogenic transmission electron tomography and deep learning, EPFL researchers have provided a first look at the nanostructure of platinum catalyst layers, revealing ...

Hydrogen fuel cells are widely recognized as a clean and high-efficiency alternative to fossil energy, but commercial ...

A fuel cell is almost like a battery that has replenishable fuel. Instead of charging a battery with an electric current, you recharge a fuel cell with something like hydrogen or you simply consume it ...

A precise synthesis tunes platinum skin thickness on PtCu nanospheres and shows two atomic layers give the best oxygen ...

When an LNO catalyst with a nickel-rich surface carries out a water-splitting reaction, its surface atoms rearrange from a cubic to a hexagonal pattern and its efficiency doubles. Deliberately ...
