Abstract:Hydrogen spillover (H-spillover) is the surface migration of activated hydrogen atoms from a metallic particle on which they are generated onto a support. The phenomenon has been widely studied because of its implication in hydrogen storage and in catalytic reactions involving hydrogen. Its existence on carbon materials is well established, but questions remain regarding its mechanism and the involvement of surface oxygen groups. In this study, we combined experimental work with chemical modeling to study the … Show more
