Eco-friendly renewable energy sources have recommended as fossil fuel alternatives in recent years to reduce environmental pollution and meet future energy demands in various sectors. As the largest source of renewable energy in the world, lignocellulosic biomass has received considerable interest from the scientific community to advance the fabrication of biofuels and ultrafine value-added chemicals. For example, biomass obtained from agricultural wastes could catalytically convert into furan derivatives. Among furan derivatives, 5-hydroxymethylfurfural (HMF) and 2, 5-dimethylfuran (DMF) are considered the most useful molecules that can be transformed into desirable products such as fuels and fine chemicals. Because of its exceptional properties, e.g., water insolubility and high boiling point, DMF has studied as the ideal fuel in recent decades. Interestingly, HMF, a feedstock upgraded from biomass sources can easily hydrogenate to produce DMF. In the present review, the current state of the art and studies on the transformation of HMF into DMF using noble metals, non-noble metals, bimetallic catalysts, and their composites have discussed elaborately. In addition, comprehensive insights into the operating reaction conditions and the influence of employed support over the hydrogenation process have demonstrated.
近年来，环保型可再生能源被推荐作为化石燃料的替代品，以减少环境污染并满足各行业未来的能源需求。作为世界上最大的可再生能源来源，木质纤维素生物质受到了科学界的广泛关注，以推动生物燃料和超细增值化学品的制造。例如，从农业废弃物中获得的生物质可以催化转化为呋喃衍生物。在呋喃衍生物中，5-羟甲基糠醛（HMF）和2,5-二甲基呋喃（DMF）被认为是最有用的分子，可以转化为理想的产品，如燃料和精细化学品。由于其特殊性质，如不溶于水和高沸点，DMF在近几十年中被研究作为理想燃料。有趣的是，从生物质来源升级的原料HMF可以很容易地氢化生成DMF。在本综述中，详细讨论了使用贵金属、非贵金属、双金属催化剂及其复合材料将HMF转化为DMF的当前技术水平和研究。此外，还展示了对操作反应条件以及所用载体对氢化过程影响的全面见解。
