由5-羟甲基糠醛（HMF）合成2，5-二甲基呋喃（DMF）是一种非常有吸引力的可再生燃料路线。然而，在该反应中实现高产率是一个巨大的挑战。在这里，它是如何描述的PtCo纳米粒子的直径为3.6 +/- 0.7 nm可以解决这个问题。在PtCo催化剂上，HMF的转化率在10分钟内为100%，2小时后DMF的产率达到98%，这大大超过了文献中报道的最佳结果。此外，该合成方法可以推广到其他空心碳球包裹的纳米颗粒。
The synthesis of 2,5-dimethylfuran (DMF) from 5-hydroxymethylfurfural (HMF) is a highly attractive route to a renewable fuel. However, achieving high yields in this reaction is a substantial challenge. Here it is described how PtCo bimetallic nanoparticles with diameters of 3.6 +/- 0.7 nm can solve this problem. Over PtCo catalysts the conversion of HMF was 100% within 10 min and the yield to DMF reached 98% after 2 h, which substantially exceeds the best results reported in the literature. Moreover, the synthetic method can be generalized to other bimetallic nanoparticles encapsulated in hollow carbon spheres.
