摘要
作为高效、清洁能源,氢能被认为是新能源发展的方向之一。使用高含氢化合物储氢材料是有效解决安全、高效地储运氢气的一种方法。其中,水合肼、硼烷氨和硼氢化物具有较高氢质量密度,可以用作化学储氢物质。为了使储氢化合物在常温常压下获得高效的氢气释放,我们设计并通过动力学控制的自组装过程制备了一系列几类多级结构纳米合金复合催化材料,包括NiCo/NiO-Co_3O_4超薄层复合结构,NiCo-Pt多面体镶嵌结构、和Ag@C@Co&Ni双壳层纳米电缆结构等。对上述纳米合金复合催化材料用于化学储氢物质的释氢催化活性、选择性、稳定性以及循环使用寿命进行了系统研究,结果表明所设计的纳米复合材料在化学储氢物质的有效催化释氢上有很好的效果,展示出了这些纳米材料催化产氢方面的重要价值。
For the purpose of high performance toward the catalysis of H_2 generation, serials of multilevel structured alloy composite catalytic nanomaterials, H_2 generation, NiCo/Ni O-Co_3O_4, Ag@C@Co, NiCo-Pt, etc., have been synthesized through the dynamics controlling assembly process, and applied to H_2 generation from ammonia borane aqueous, potassium borohydride and hydrous hydrazine under ambient atmosphere at room temperature. The performances of activity, selectivity, stability, and life-time are investigated in detail. As-prepared nanomaterials exhibit their value in catalyzing H_2 generation from chemical H_2 compounds in practical applications.
