Proton exchange membrane (PEM) water electrolysis is an important technology to produce large-scale green hydrogen. Platinum on Carbon (Pt/C) is a state-of-the-art cathode catalyst due to its moderate ...

The schematic diagram reveals that the stabilizing effect of iridium single atoms during the acidic oxygen evolution reaction is determined by their anchoring sites. Single atoms anchored at lattice ...

At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum tunneling, the passage of an atom through a barrier with a higher potential energy ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...
