The catalytic dehydrogenation of hydrazine borane (N2H4BH3) and hydrous hydrazine (N2H4·H2O) for H2 evolution is considered as two of the pivotal reactions for the implementation of the hydrogen-based economy. A reduction rate controlled strategy is successfully applied for the encapsulating of uniform tiny NiPt alloy nanoclusters within the opening porous channels of MOFs in this work. The resultant Ni0.9Pt0.1/MOF core–shell composite with a low Pt content exerted exceedingly high activity and durability for complete H2 evolution (100% hydrogen selectivity) from alkaline N2H4BH3 and N2H4·H2O solution. The features of small NiPt alloy NPs, strong synergistic effect between NiPt alloy NPs and the MOF, and open pore structure for freely mass transfer made NiPt/MIL-101 an excellent catalyst for highly efficient H2 evolution from N2H4BH3 or N2H4·H2O.

MOF封装的NiPt纳米粒子的控制合成，以从肼硼烷和肼高效高效地制氢
肼硼烷（N 2 H 4 BH 3）和含水肼（N 2 H 4 ·H 2 O）催化脱氢以生成H 2被认为是实现氢基经济的两个关键反应。在这项工作中，成功地将还原速率控制策略用于将均匀的细小NiPt合金纳米团簇封装在MOF的开口多孔通道中。低Pt含量的Ni 0.9 Pt 0.1 / MOF核-壳复合材料具有极高的活性和耐久性，可从碱性N完全析出H 2（氢选择性为100％）2 H 4 BH 3和N 2 H 4 ·H 2 O溶液。NiPt合金小NPs的特征，NiPt合金NPs与MOF的强协同作用以及自由传质的开孔结构使NiPt / MIL-101成为从N 2 H 4 BH 3或H 2高效释放H 2的极佳催化剂。ñ 2 ħ 4 ·H 2 O.
