sustainable Pd/SiO 2 nanospheres catalyst. Further, its catalytic activity was demonstrated for the direct reductive coupling of nitroarenes under mild conditions. While the reaction with Pd nanoparticles on other supporting materials such as modified carbon materials and TiO 2 , under similar conditions, resulted formation of amines exclusively. Therefore, it was confirmed that the SiO 2 was found to
摘要 在本研究中,我们合成了一种稳健且可持续的 Pd/SiO 2 纳米球催化剂。此外,其在温和条件下对硝基芳烃的直接还原偶联具有催化活性。而在类似条件下,与其他载体材料(如改性碳材料和 TiO 2 )上的 Pd 纳米颗粒反应,只会形成胺。因此,证实SiO 2 被发现是对硝基芳烃的选择性还原偶联的最佳支持材料。此外,催化剂可以循环使用多达五个循环,产品收率略有损失(< 2% 收率)。图形摘要
