摘要：

Highly dispersed bimetallic NiPt nanoparticles with different NiPt compositions have been successfully immobilized by the zeolitic metal-organic framework ZIF-8 by a simple liquid impregnation method. These catalysts show high catalytic activity and durability for hydrogen generation from decomposition of hydrazine (H2NNH2) in aqueous alkaline solution at 323K. Both transmission electron microscopic (TEM) and high-angle annular dark-field scanning TEM measurements (HAADF-STEM) images showed that the ZIF-8 immobilized NPs were highly dispersed and controlled in small sizes with an average diameter of 2.2 +/- 0.3nm.
