SBA-15 is considered as an ideal support to ensure a copper-based catalyst with high activity and selectivity. In this work, the hydrogenation of diethyl malonate (DEM) to 1,3-propanediol (1,3-PDO) over Cu/SBA-15 catalysts was investigated. Compared to the conventional Cu/SiO₂ catalyst, the Cu/SBA-15 catalysts exhibited higher DEM conversions (up to 95%), better 1,3-PDO selectivities (up to 61%), and longer lifetime (over 180 h). These improvements were ascribed to the well-ordered tubular channel structure, better copper active-site dispersion, and appropriate Cu⁺/Cu° ratio in the Cu/SBA-15, affording higher TOFs and copper species surface areas, which was confirmed by N₂-physisorption, X-ray diffraction, inductively coupled plasma-atomic emission spectroscopy, N₂O titration, transmission electron microscopy, H₂ temperature-programmed reduction, Fourier-transform infrared spectroscopy, and X-ray photoelectron spectroscopy analyses. The Cu/SBA-15 in this work advances the prospects of DEM hydrogenation as a promising method to produce 1,3-PDO on industrial scale.

SBA-15被认为是确保铜基催化剂具有高活性和选择性的理想载体。在这项工作中，研究了在Cu / SBA-15催化剂上将丙二酸二乙酯（DEM）加氢成1,3-丙二醇（1,3-PDO）。与传统的Cu / SiO ₂催化剂相比，Cu / SBA-15催化剂显示出更高的DEM转化率（高达95％），更好的1,3-PDO选择性（高达61％）和更长的使用寿命（超过180小时） 。这些改进归因于良好的管状通道结构，更好的铜活性位点分散以及Cu / SBA-15中适当的Cu ⁺ / Cu°比，从而提供了更高的TOF和铜物种表面积，这一结果已由N证实。_2个-物理吸附，X射线衍射，电感耦合等离子体原子发射光谱，N ₂ O滴定，透射电子显微镜，H _2程序升温还原，傅里叶变换红外光谱和X射线光电子能谱分析。这项工作中的Cu / SBA-15推动了DEM加氢的前景，因为它是一种在工业规模上生产1,3-PDO的有前途的方法。
