制备了以席夫碱修饰的OMS-Cu（BDC）孔笼为载体的钯离子接枝催化剂，并研究了其在甲酸制氢反应中的催化性能。多孔MOF结构和Pd离子周围的Schiff基基团的作用在稳定Pd离子方面起着重要作用，提供了MOF载体和Pd位点之间的强相互作用。在无添加剂的情况下，Pd-Schiff碱配合物对甲酸的脱氢反应具有良好的催化活性，生成147 mL气体（H2 + CO2），转化频率（TOF）值为412 h（-1）。该非均相分子催化剂通过过滤可以很容易地回收，并且在重复使用过程中几乎没有活性损失。结果表明，该非均相Pd基Cu-MOF是一种很有前途的甲酸制氢催化剂。
Catalysts based on palladium ions grafted on Schiff-base decorated OMS-Cu(BDC) pore cage were prepared and their catalytic performance in the hydrogen generation from formic acid was studied. The effects of the porous MOF structure and Schiff-based group presented around the Pd ions play important roles in stabilizing the Pd ions, providing strong interaction between the MOF support and Pd site. The Pd-Schiff base complex grafted on Cu-MOF exhibits excellent catalytic activity to produce 147 mL of gas (H-2 + CO2) with the turnover frequency (TOF) value of 412 h(-1) towards the dehydrogenation of formic acid without any additives. The heterogeneous molecular catalyst could be easily recycled through the filtration and almost has no activity loss during the reuse. The results revealed that the heterogeneous Pd-based Cu-MOF is a promising catalyst for the hydrogen generation from formic acid.
