通过离子交换法用不同的铜前驱体合成的 Cu/HMS 催化剂已经被系统地表征，重点关注铜前驱体的影响。研究发现，干燥、煅烧和还原的Cu/HMS材料的织构、表面成分和表面结构受到铜前驱体种类的深刻影响。根据表征，对干燥、煅烧和还原样品中的铜形态进行了分配。适当的铜前体可能有利于活性铜物质的生成；因此可以获得增强的催化性能。通过优化气体加氢反应条件，以Cu(NH3)4(NO3)2为铜前驱体，通过Cu-HMS催化剂可以获得98%的乙二醇收率。
Cu/HMS catalysts synthesized with different copper precursors via the ion exchange method have been systematically characterized, focusing on the influence of copper precursors. It is found that the texture, surface composition and the surface structure of the dried, calcined and reduced Cu/HMS materials were profoundly affected by the kinds of copper precursors. Based on the characterizations, the copper species on dried, calcined and reduced samples were assigned. Proper copper precursor could be beneficial for the generation of active copper species; enhanced catalytic performance could thus be obtained. By optimizing the gas-hydrogenation reaction conditions, an ethylene glycol yield of 98% could be obtained via the Cu–HMS catalyst using Cu(NH3)4(NO3)2as the copper precursor.
