Herein, we report that highly dispersed copper–cobalt mixed metal/metal oxide nanoparticles embedded into three-dimensional porous carbon were highly catalytic active nanocomposites for transforming bioderived furfural (FAL) to cyclopentanone (CPO) via aqueous-phase hydrogenation/rearrangement. This simple and efficient catalyst was prepared by controlled pyrolysis procedure using glucose as the carbon source at 500 °C under N₂ atmosphere. Characterization of the as-prepared CuCo_0.8@C-500 catalyst by XRD, STEM, SEM, TEM, and XPS suggested that there was a synergism between copper and cobalt. Under an extremely low H₂ pressure (0.5 MPa), 90.2% yield of CPO could be attained at 150 °C. In addition, the sample could be recycled for several times without decrease in catalytic activity. Two critical reaction intermediates of furfuryl alcohol (FOL) and 2-cyclopentenone (2-CPE) were detected in the tandem catalytic process. These results demonstrated that this synthetic strategy represented a simple and effective way for utilization of inexpensive biomass resources to obtain some valuable chemicals.

原位合成高度分散的Cu-Co双金属纳米颗粒，用于水相中生物衍生糠醛的串联加氢/重排。

在本文中，我们报道了嵌入三维多孔碳中的高度分散的铜-钴混合金属/金属氧化物纳米颗粒是通过水相加氢/重排将生物衍生糠醛（FAL）转化为环戊酮（CPO）的高催化活性纳米复合材料。这种简单有效的催化剂是通过在N ₂气氛下，以葡萄糖为碳源，在500°C下，通过控制热解程序制备的。XRD，STEM，SEM，TEM和XPS对制得的CuCo _0.8 @ C-500催化剂的表征表明，铜和钴之间存在协同作用。在极低的H _2下在150℃的压力（0.5 MPa）下，CPO的收率为90.2％。另外，样品可以循环使用几次而不会降低催化活性。在串联催化过程中检测到了糠醇（FOL）和2-环戊烯酮（2-CPE）的两个关键反应中间体。这些结果表明，这种合成策略代表了一种利用廉价生物质资源以获得某些有价值的化学品的简单有效的方法。
