碳基金属或金属氧化物纳米复合材料在许多领域发挥着重要作用。通过焙烧Cu-MOF-74，制备了石墨碳层负载的Cu-Cu_2 O纳米复合材料（简称Cu-Cu_2 O-C），该复合材料在可见光下对苯乙炔偶联合成1，4-二苯基丁二炔具有上级活性，这是由于Cu-Cu_2 O-C中三组分的协同作用。该催化剂是高效的，并且可以容易地回收。上级已经报道的苯乙炔偶联系统，只有可见光和一个非常低的量的铜（1.65摩尔%），需要在我们的系统。该研究为可见光诱导苯乙炔偶联反应提供了一种很有前途的策略，并突出了利用金属有机骨架作为前体获得碳载金属/金属氧化物纳米复合材料用于多相协同催化的巨大潜力。
Carbon-based metal or metal oxide nanocomposites have played an essential role in many fields. In this work, we reported that graphitic-carbon-layer-supported Cu-Cu2O nanocomposites (denoted as Cu-Cu2O-C) can be obtained via calcination of Cu-MOF-74, which shows superior activity for coupling of phenylacetylene to form 1,4-diphenylbutadiyne under visible light because of the synergistic action of the three components in the as-formed Cu-Cu2O-C. The catalyst is highly efficient and can be facilely recycled. Superior to the already reported phenylacetylene coupling systems, only visible light and a very low amount of copper (1.65 mol %) is required in our system. This study provides a promising strategy for visible-light-induced phenylacetylene coupling and highlights the great potential of using metal-organic frameworks as precursors to obtain carbon-supported metal/metal oxide nanocomposites for heterogeneous cooperative catalysis.
