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.
2,5-二甲基呋喃(DMF)由 5-羟甲基糠醛(HMF)合成是一条极具吸引力的可再生燃料路线。然而,在该反应中实现高收率是一个巨大的挑战。本文描述了如何通过直径为 3.6 ± 0.7nm 的 PtCo 双金属纳米颗粒解决这个问题。在 PtCo 催化剂上,HMF 的转化率在 10 分钟内达到 100%,2 小时后 DMF 的收率达到 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封装在中空碳球中的双金属纳米颗粒。
