Graphene doped with nitrogen and augmented with cobalt atoms has proven to be an effective, durable catalyst for the production of hydrogen from water, according to scientists at Rice University.

As no direct coordination via the nitrogen atom took place, the researchers assume a reaction from the gas phase with a potential activation on the ammonia molecule.

This results in defects in the lattice structure: some few carbon atoms — fewer than 1 % — separate from the lattice and are replaced with nitrogen atoms, which bring along additional electrons.

After breaking away from the molecule in the strong laser field, the electron returned and was scattered on a molecular ion, which resulted in the molecule dissociation into a positive nitrogen ion and an oxygen atom.

The final, prolonged emission was from the breakdown of now neutron - poor and unstable nitrogen atoms.
