Hydrodeoxygenation (HDO) is an attractive route for the upgrading of bio-oils produced from lignocellulose. Current catalysts require harsh conditions to effect HDO, decreasing the process efficiency in terms of energy and carbon balance. Herein we report a novel and facile method for synthesizing bimetallic PtCo nanoparticle catalysts (ca. 1.5 nm) highly dispersed in the framework of nitrogen-doped ordered mesoporous carbon (NOMC) for this reaction. We demonstrate that NOMC with either 2D hexagonal (p6m) or 3D cubic (Im3‾ m) structure can be easily synthesized by simply adjusting the polymerization temperature. We also demonstrate that PtCo/NOMC (metal loading: Pt 9.90 wt %; Co 3.31 wt %) is a highly effective catalyst for HDO of phenolic compounds and "real-world" biomass-derived phenolic streams. In the presence of PtCo/NOMC, full deoxygenation of phenolic compounds and a biomass-derived phenolic stream is achieved under conditions of low severity.
水相脱氧（HDO）是一种将木质纤维素生物油升级的有吸引力的途径。目前的催化剂需要苛刻的条件才能进行 HDO，从而降低了能量和碳平衡方面的工艺效率。在此，我们报告了一种用于合成负载在氮掺杂有序介孔碳（NOMC）中的双金属 PtCo 纳米颗粒催化剂（约 1.5nm）的新颖且简便的方法，用于该反应。我们证明，通过简单地调整聚合温度，可以很容易地合成具有二维六方（p6m）或三维立方（Im3‾ m）结构的 NOMC。我们还证明，PtCo/NOMC（金属负载：Pt 9.90wt%；Co 3.31wt%）是酚类化合物和“真实世界”生物质衍生酚类物流 HDO 的高效催化剂。在 PtCo/NOMC 的存在下，在低苛刻条件下实现了酚类化合物和生物质衍生酚类物流的完全脱氧。
