Pd nanocatalyst supported on amine-functionalized mesoporous graphitic carbon nitride (Pd/NH2-mpg-C3N4) was investigated for dehydrogenation of formic acid. The catalyst was analyzed and tested to investigate the effect of amine functionalization on hydrogen generation from formic acid. Pd nanocatalyst was dispersed uniformly on NH2-mpg-C3N4 without agglomeration. The turnover frequency value of Pd/NH2-mpg-C3N4 was 1870 h−1, which was higher than that of Pd/mpg-C3N4 because of the amine functionalization. The Pd/NH2-mpg-C3N4 was also tested to investigate the effect of various reaction conditions (formic acid concentration, sodium formate concentration, and reaction temperature) on hydrogen generation from formic acid. Formic acid concentration negatively affected the catalytic activity, whereas sodium formate concentration positively affected it. Reaction temperature significantly affected the catalytic activity. The apparent activation energy of the Pd/NH2-mpg-C3N4 catalyst was 60.7 kJ mol−1, and a hydrogen generator with the catalyst exhibited high conversion efficiency at an elevated temperature. Consequently, a hydrogen generator with Pd/NH2-mpg-C3N4 is suitable for polymer electrolyte membrane fuel cell systems. |
