摘要

2,5-呋喃二甲酸（FDCA）是生产高附加值绿色聚合物的极佳前体，近来备受关注。传统的将 5-羟甲基糠醛（HMF）氧化成 FDCA 的方法通常需要高压、高温等苛刻条件和非环保反应物，因此既不环保也不经济。在本研究中，我们提出了一种新型光催化系统，利用等离子体天线效应来增强铈（CeO2）上的钯团簇。该系统可在环境条件下驱动 HMF 向 FDCA 的转化，在绿光照射下，4 小时内的产率超过 90%，令人印象深刻。值得注意的是，该系统中的钯含量极低。这一发现可为开发具有不同纳米结构或元素组成的新型光催化系统铺平道路，从而实现高效的化学反应。

Plasmonic antenna enhancement on Pd cluster towards high selective FDCA production

2,5-Furandicarboxylic acid (FDCA), an excellent precursor for producing value-added green polymers, has recently garnered much attention. Traditional methods for oxidizing 5-Hydroxymethylfurfural (HMF) to FDCA typically require harsh conditions, such as high pressure, high temperature, and non-eco-friendly reactants, making them neither green nor economical. In this study, we present a novel photocatalytic system utilizing a plasmonic antenna effect to enhance Pd clusters supported on ceria (CeO₂). This system drives the transformation from HMF to FDCA under ambient conditions, achieving an impressive yield of over 90% within 4 h under green light irradiation. Notably, the palladium content in this system is minimal. This discovery could pave the way for the development of new photocatalytic systems with varied nanostructures or elemental compositions for efficient chemical reactions.
