纳米碳球负载钯纳米粒子催化合成1,10-邻菲咯啉-5,6-二胺

Synthesis of 5,6-diamino-1,10-phenanthroline Catalyzed with Nano-Pd/C

利用水热合成技术制备的胶态纳米碳球被用作载体和还原剂制备得到了纳米碳球固载钯纳米粒子(Nano Pd/C),并被用作1,10-邻菲咯啉-5,6-二胺合成反应的催化剂。考察了Nano Pd/C材料制备过程中PdC l2浓度、催化反应时间对其催化1,10-邻菲咯啉-5,6-二胺合成反应活性的影响。结果表明,该Nano Pd/C材料对1,10-邻菲咯啉-5,6-二胺的合成表现出优秀的催化活性,与常规Pd/C催化剂相比,将反应时间由12 h缩短到6 h,并使1,10-邻菲咯啉-5,6-二胺的产率由83%提高到90%。

The colloidal carbon nano-spheres synthesized by means of the hydrothermal method were used as support and reductant to synthesize Nano-Pd/C material. This Nano-Pd/C material could be used as catalyst in the synthese of 5,6-diamino-1,10-phenanthroline and its catalytic activity was studied systematically. The experiment results show that the Nano-Pd/C catalyst can decrease the reaction time from 12 h to 6 h while increase the yield from 83% to 90%.
