Abstract

Hydrogen interaction with gold nanoparticles deposited on the surface of a highly oriented pyrolytic graphite is determined by the external potential ϕ of the sample with respect to the ground. It is demonstrated that, at ϕ > +1 V, molecular hydrogen does not practically interacts with hydrogen, whereas at ϕ ≤ 0 V, such interaction is possible.
