由三聚氰胺-间苯二酚-甲醛水凝胶合成的N掺杂碳干凝胶被用作制备用于甲酸脱氢反应的Pd基催化剂的载体。研究了碳干凝胶的孔结构和氮含量对产氢催化活性的影响。据观察，与不含 N 的对应物相比，在明确的微介孔碳干凝胶中适当的氮掺杂能够制备出对甲酸脱氢具有明显增强的催化增强的 Pd 催化剂，达到 2014h−1 的初始 TOF 值。
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.
