Effects of N-doping of carbon nanofibers and mesoporous graphene like carbon were studied for hydrogen production by decomposition of formic acid over Pt, Pd and Ru clusters of less than 3 nm size. N-doping of the supports (6-7 at.% N) provides a considerable increase of the formic acid decomposition rate (up to 10 times for Pt), selectivity to hydrogen (from 96.2 to 99.5% for Pt) and resistance to CO inhibition. This could be related to the presence of electron-deficient clusters and isolated atoms of metals stabilized by pyridinic nitrogen on the open edge graphene sites; these can dehydrogenate an intermediate adduct of formic acid with pyridinic nitrogen (>NH+HCOO-) to give hydrogen and carbon dioxide. The N doped Pd and Pt catalysts showed the highest activity in the hydrogen production.
