[Display omitted] •Pd/N-doped carbon xerogels for the formic acid dehydrogenation were synthetized.•The effect of pore texture and N content was investigated.•The presence of N-functionalities is beneficial for the final catalytic activity.•An initial TOF value of 2014 h−1 on the basis of the total Pd loading was obtained. N-doped carbon xerogels synthesized from melamine-resorcinol-formaldehyde aqueous gels were used as supports for the preparation of Pd-based catalysts for the formic acid dehydrogenation reaction. The effect of the pore texture and nitrogen content of the carbon xerogels on the catalytic activity for the hydrogen production was investigated. It was observed that an appropriate nitrogen doping in a well-defined micro-mesoporous carbon xerogel enables the preparation of Pd catalysts with appreciable catalytic enhancement towards the formic acid dehydrogenation as compared to the N-free counterpart, reaching an initial TOF value of 2014 h−1.
