Abstract

The efficient oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) was achieved using the nano CuO catalyst in a NaClO solution. This study revealed that the particle size of the nano CuO could be effectively regulated by adjusting the calcination temperature, thereby significantly improving the catalytic performance of HMF oxidation to the desired product FDCA. Notably, the CuO-100 catalyst with the smallest particle size exhibited superior HMF conversion and maximum FDCA yield (96.0%). Moreover, even with a reduced NaClO/HMF molar ratio of 7.3:1 to improve the utilization of NaClO, the 94.7% yield of FDCA was obtained on the CuO-100 catalyst.

纳米氧化铜催化剂高效氧化5-羟甲基糠醛制2,5-呋喃二羧酸

采用纳米CuO催化剂，在NaClO溶液中实现了5-羟甲基糠醛（HMF）高效氧化制2,5-呋喃二羧酸（FDCA）。本研究发现，通过调节煅烧温度可以有效调节纳米CuO的粒径，从而显著提高HMF氧化制备所需产物FDCA的催化性能。值得注意的是，粒径最小的CuO-100催化剂表现出优异的HMF转化率和最高的FDCA收率（96.0%）。此外，即使将NaClO/HMF的摩尔比降低到7.3:1以提高NaClO的利用率，在CuO-100催化剂上，FDCA的收率也达到了94.7%。

期刊介绍： ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies. Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
