摘要

构建限域于SBA-15介孔通道内的双金属铜钴纳米颗粒催化剂（CuCo/SBA-15）。通过X射线衍射、N₂物理吸附和扫描电子显微镜等多尺度表征,证实该限域结构可有效调控活性组分的粒径分布,并可增强铜钴组分间的电子协同效应。在合成气制高级醇的反应中,CuCo/SBA-15催化剂展现出41.6%的高级醇选择性,特别是C₁~C₄混合醇的分布显著窄化,占比超过86.3%。

Abstract

Anovel SBA-15 mesoporous channel limited bimetallic Cu-Co NPs catalyst (CuCo/SBA-15） was constructed. The catalyst was characterized by X-ray diffraction （XRD）, N₂ adsorption-desorption characteristics and scanning electron microscopy (SEM）, confirming that the confined structure can effectively regulate the particle size distribution of the active components and enhance the electronic synergy between the Cu and Co components. The results show that in the reaction of higher alcohol synthesis from syngas, the CuCo/SBA-15 catalyst achieved a higher alcohol selectivity of 41.6%. In particular, the distribution of C₁-C₄ mixed alcohols was significantly narrowed, accounting for over 86.3%.
