Ethylenediamine bisborane (EDAB), containing 11.49% hydrogen by weight, ranks third among notable amine boranes in terms of hydrogen content and has some advantages due to the limit the practical use of AB for the applications of hydrogen storage. In this work, EDAB was synthesized and its catalytic hydrolysis was studied for the hydrogen production. For this purpose, Ni/Ni_xB_yZr and PdNi/Ni_xB_yZr catalysts were prepared by using the co-precipitation with NaBH₄ and impregnation method. XRD, XPS, SEM–EDX, and multi-point BET were used to characterize catalysts. Reusability test, kinetic analyses were done. It has been observed that both Ni/ Ni_xB_yZr and PdNi/ Ni_xB_yZr catalysts enhance the hydrogen production yield and reduces the reaction time. The highest hydrogen production yield and the shortest reaction time of EDAB hydrolysis were reached as 99.67% and 215 s at 55°C with PdNi/Ni_xB_yZr catalyst. The catalytic efficacy of PdNi/Ni_xB_yZr catalyst is 115.58 mL min⁻¹ g⁻¹, for the hydrolysis of EDAB at 298 K. Activation energy for Pd-Ni/Ni_xB_yZr and Ni/Ni_xB_yZr catalysts were reported as 27.04 and 53.81 kJ.mol⁻¹.

Ni/NixBy?Zr 和 Pd-Ni/NixBy?Zr 作为高活性催化剂水解乙二胺双硼烷制氢

乙二胺双硼烷（EDAB）的氢含量为11.49%，按氢含量计算，在著名的胺硼烷中排名第三，并且由于AB在储氢应用中的实际使用受到限制，因此具有一些优势。在这项工作中，合成了 EDAB 并研究了其催化水解产氢。为此，采用NaBH ₄共沉淀法和浸渍法制备了Ni/Ni _x B _y  Zr和Pd  Ni/Ni _x B _y  Zr催化剂。使用 XRD、XPS、SEM-EDX 和多点 BET 来表征催化剂。进行了可重复使用性测试、动力学分析。据观察，Ni/ Ni _xB _y  Zr 和 Pd  Ni/ Ni _x B _y  Zr 催化剂提高了氢气产率并缩短了反应时间。在Pd  Ni/Ni _x B _y  Zr催化剂下，EDAB水解的最高产氢率和最短反应时间在55℃下达到99.67%和215 s 。Pd  Ni/Ni _x B _y  Zr 催化剂在 298 K 下对 EDAB 水解的催化效率为 115.58 mL min ⁻¹  g ^{−1 。Pd-Ni/Ni} _x B _y 的活化能Zr和Ni/Ni _x B _y  Zr催化剂报道为27.04和53.81 kJ.mol ^-1。
