长期以来，人们一直在探索利用生物质作为一种解决办法，以满足对完全可持续的生物商品工业的迫切需要。然而，取得的成功有限。在这项研究中，一个高效的两阶段程序直接制备对二甲苯（PX）从5-羟甲基糠醛（HMF）和甲酸在一锅;这些化学品是两个主要的生物基原料，提供了潜在的解决迫切需要的绿色，可持续生产的drop-in化学实体。使用一个强大的，有效的多相催化剂，即，钯修饰的Au簇锚定在四方相氧化锆，是至关重要的成功，这一战略。这种多功能催化体系不仅可以促进由HMF快速、几乎唯一地形成2，5-二甲基呋喃（DMF）的低能-势垒无H-2-途径，而且还可以通过所得DMF与乙烯的脱水芳构化实现随后的超选择性生产PX。
The use of biomass as a solution to satisfy the pressing needs for a fully sustainable biocommodity industry has been explored for a long time. However, limited success has been obtained. In this study, a highly effective two-stage procedure for the direct preparation of para-xylene (PX) from 5-hydroxymethylfurfural (HMF) and formic acid in one pot is described; these chemicals are two of themajor bio-based feedstocks that offer the potential to address urgent needs for the green, sustainable production of drop-in chemical entities. The use of a robust, efficient heterogeneous catalyst, namely, bimetallic Pd-decorated Au clusters anchored on tetragonal-phase zirconia, is crucial to the success of this strategy. This multifunctional catalytic system can not only facilitate a lowenergy- barrier H-2-free pathway for the rapid, nearly exclusive formation of 2,5-dimethylfuran (DMF) from HMF but also enable the subsequent ultraselective production of PX by the dehydrative aromatization of the resultant DMF with ethylene.
