在有适当催化剂存在的前提下，硼氢化钠水解放氢速率可显著提高，这成为影响其放氢的关键因素。然而，活性较高的的催化剂多为Pt、Au、Ru基等贵金属材料。Cu基非贵金属材料具有成本低以及高效的催化活性而备受关注，尤其是尺寸处于5nm以下的超细纳米粒子。本项目以此为切入点，采用一步化学沉积法可控合成超细纳米双金属CuM（M=Co，Fe）材料作为催化剂；采用XRD、SEM、TEM、AFM、XPS、BET等实验检测手段，研究催化材料的物相组成、微观结构、晶粒尺寸、表面组成、比表面等因素对硼氢化钠制氢性能的影响，建立材料的微观表面性质与催化性能之间的关联；通过催化反应中间产物的原位监测与理论设计、理论计算相结合，推断其反应机理，进而从根本上提出高效催化剂应具备的物化特征，本项目旨在揭示影响催化剂性能的关键因素，对硼氢化钠制氢研究具有重要意义。

To effectively control the hydrolysis of the alkaline sodium borohydride solution, it is necessary to use appropriate catalysts. Although noble metal catalysts, like Pt-based Au-based and Ru-based catalysts, show higher catalytic activity, they are more expensive. The Cu-based catalysts are needed to be more systematically and deeply studied due to the low cost and high stability. One-step electroless deposition method are used to synthesize ultrafine bimetallic CuM (M=Co, Fe) nanoparticles. The catalysts will be characterized through XRD, SEM, TEM, AFM, XPS, BET and so on. The phase composition, crystal structure, crystallite size, surface composition and specific surface area of the as-obtained catalysts will be studied. Moreover, the research on how the above-mentioned factors influence the catalytic activity will be discussed to prepare the ultrafine bimetallic Cu-based nanoparticles catalysts with the high catalytic performance. It will be pointed out that the high efficiency catalyst should show the structure characteristics to establish the relationship between the catalytic activity and the physical properties of the materials. On the basis of the detection of the intermediate and the simulation of the reaction, the reaction mechanism of the hydrogen evolution from sodium borohydride will be inferred. The project aims to reveal the crucial factor of influencing on the catalytic performance. It will be significant to research the hydrogen generation of sodium borohydride.
