Research Progress of Highly Efficient Noble Metal Catalysts for the Oxidation of 5‐Hydroxymethylfurfural

5‐hydroxymethylfurfural (HMF) is considered to be one of the most pivotal multifunctional biomass platform chemicals. This Review discusses recent advances in catalytic oxidation of HMF towards high‐value products. The reaction mechanism of different noble metals and the path of HMF oxidation to high‐value products have been deeply investigated in the noble metal catalytic system. The reaction mechanisms of different noble metals and HMF conversion paths were compared in detail. Moreover, the factors affecting the performance of different noble metal catalysts were summarized. Finally, effective strategies were put forward to improve the catalytic performance of noble metal catalysts. The purpose is to provide a valuable reference for the academic research on the preparation of oxidation products from biomass‐based HMF and the industrial application of noble metal catalysts. HMF oxidation: 5‐Hydroxymethylfurfural (HMF) is one of the most pivotal multifunctional biomass platform chemicals. HMF is upgraded to high‐value products via oxidation, which plays an important role in creating huge economic value for biomass products. Noble metal catalysts have excellent catalytic activity for HMF oxidation. This Review summarizes and compares the HMF oxidation methods and mechanisms in different noble metal catalytic systems.
