A highly dispersed Cu-O-Si composite oxide framework catalyst with high surface area (619 m²/g) and very small particle size (~3 nm) has been synthesized using an improved precipitation method, which showed high catalytic activity toward the hydrogenation of dimethyl oxalate (DMO) (99.9% conversion of DMO and 96.7% selectivity for ethylene glycol) even at low temperature (175 °C). In addition, its chemical stability was significantly enhanced due to the formation of a Cu-O-Si composite structure and the low reaction temperature, and the catalyst did not show any significant inactivation during the stability test over 140 h.

使用改进的沉淀法合成了具有高表面积（619 m ² / g）和非常小的粒径（〜3 nm）的高度分散的Cu-O-Si复合氧化物骨架催化剂，该催化剂对氢化反应显示出很高的催化活性。草酸二甲酯（DMO）的转化率（DMO的转化率为99.9％，对乙二醇的选择性为96.7％），即使在低温（175°C）下也是如此。此外，由于形成了Cu-O-Si复合结构和较低的反应温度，其化学稳定性得到了显着提高，并且在140 h的稳定性测试过程中，该催化剂没有出现任何明显的失活现象。
