摘要: The invention relates to a LiAlH4/carbon-coated metal nanoparticle (Ni-Co@C) composite hydrogen storage material and a preparation method thereof. Carbon-coated Ni-Co bimetal nanoparticles (Ni-Co@C) with a uniform diameter of 4-6nm are prepared by taking CoCo(Ni(EDTA))2.4H2O as a precursor through a high-temperature sintering method; Ni-Co@C is taken as a catalyst for compounding with LiAlH4, so that the hydrogen desorption temperature of a LiAlH4 system is greatly reduced; when the doping amount of the catalyst is 1wt%, the hydrogen desorption temperature is reduced to 43 DEG C and the hydrogen desorption amount achieves 7.3wt%; and when the doping amount of the catalyst is 10wt%, the hydrogen desorption temperature achieves 36 DEG C for the first time. The catalyst (Ni-Co@C) prepared by the method disclosed by the invention has great uniform dispersion, and the prepared LiAlH4 composite hydrogen storage material can show good hydrogen desorption performance at relatively low temperature. | 本发明涉及一种LiAlH4/碳包覆金属纳米粒子(Ni-Co@C)复合储氢材料及其制备方法。以CoCo[Ni(EDTA)]2·4H2O为前驱体通过高温烧结法制备了均一的直径为4-6nm的碳包覆Ni-Co双金属纳米粒子(Ni-Co@C);以Ni-Co@C为催化剂将其与LiAlH4进行复合,大大降低了LiAlH4体系的放氢温度,当催化剂的掺杂量为1wt%时,放氢温度降至43°C,放氢量达到7.3wt%;当催化剂的掺杂量为10wt%时,放氢温度首次达到36°。本发明制备的催化剂(Ni-Co@C)具有很好的均匀分散性,制得的LiAlH4复合储氢材料能够在较低的温度下表现出良好的放氢性能。
