摘要
氢气在未来能源系统中具有十分重要的作用,但是限制氢气应用的储存、运输问题却难以解决。在众多储氢方法中,甲酸储氢是一种具有巨大应用潜力的储氢技术。本文以MOF-5派生新型纳米多孔炭材料为载体,负载AgPd纳米合金(Ag Pd/MOF-5-C)用于催化甲酸产氢反应。实验证明,该催化剂对于甲酸产氢反应时具有很高的催化活性。在30℃时,该催化剂的初始转化频率可以达到854 h~(-1)。正是由于纳米粒子的高分散度以及金属与载体间的相互作用,导致该催化剂具有较高的催化性能。
An efficient synergistic catalyst, AgPd bimetal supported on metal-organic framework derived porous carbon(AgPd/MOF-5-C), was fabricated for the first time. The catalyst exhibited 100% H_2 selectivity and high catalytic activity in hydrogen generation from formic acid at ambient conditions. The initial turnover frequency could reach as high as 854 h~(-1). The combination of distinct interaction among bimetal, support and high dispersion of nanoparticles drastically enhances the catalytic performance of the resulted catalyst.
