摘要: 通过一步法原位合成了核壳结构的Cu@CoCr三元合金催化剂,该合成方法条件温和、步骤简便。25 ℃下,Cu_0.4@Co_0.5Cr_0.1三元合金催化剂对于硼氨配合物水解反应的TOF值达到0.242 0 mol_H₂·moL_cat^-1·s^-1,接近Pt、Pd等贵金属的催化活性,反应的活化能仅为35 kJ·mol^-1,5次重复使用后仍能保持初始活性的35%。与非核壳结构的CuCoCr合金相比,核壳结构的Cu@CoCr三元合金催化剂的催化性能及稳定性均有明显提高。此外材料自身具有磁性,可进行磁分离,适合于实际应用。

Abstract: The core/shell structured ternary alloy of Cu@CoCr was synthesized by a one-step in-situ synthesis method under mild conditions. The catalytic performance of Cu@CoCr was studied for the hydrolysis of NH₃BH₃ (AB) aqueous solution. The TOF (turn over frequency) of 0.242 0 mol_H₂·moL_cat^-1·s^-1 for Cu_0.4@Co_0.5Cr_0.1 catalyst on AB hydrolysis reaction is close to the noble-metal based catalysts, such as Pt, Pd, etc. The activation energy of this catalyst is only 35 kJ·mol^-1. After 5 cycles, this catalyst still keeps 35% of its initial activity. Compared to the non-core/shell structured CuCoCr alloy, the Cu@CoCr catalyst shows great improvements in activity, stability and reusability. Furthermore, the Cu@CoCr catalysts could be recovered by a magnet based on its magnetic properties.
