▎ 摘　　要

The properties of a new catalytic Pt/N-graphene system in the gas-phase reaction of formic acid decomposition for the production of pure hydrogen were studied. Graphene powders undoped and doped with nitrogen atoms were used as carbon supports. Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (TEM), and the chemisorption of CO were used to characterize the synthesized catalysts. It was found that the activity of the catalysts increased upon graphene doping with nitrogen atoms and with increasing the platinum concentration from 0.2 to 1 wt %; the catalyst selectivity in the test reaction was as high as 96-99%.
