5-Hydroxymethylfurfural (HMF) has been identified as one of the most promising biomass-based multi-purpose platform molecules. Innovative protocols, namely electrocatalysis, photocatalysis, and microwave (MW)-assisted chemistry, as well as continuous-flow systems, add a new dimension and another promising toolbox for the oxidation of HMF in recent years. This Minireview deals with recent progress in the catalytic oxidation of HMF to 2,5-furandicarboxylic acid (FDCA) and other intermediates using noble, non-noble, and metal-free systems deploying emerging protocols. Selective HMF downstream oxidation products could be obtained not only via common catalyst modifications, namely nature of the metal, preparative method, and the property of deployed support, but also by using innovative processes.
5-羟甲基糠醛（HMF）已被确定为最有前途的基于生物质的多功能平台分子之一。近年来，创新的协议，即电催化、光催化和微波（MW）辅助化学以及连续流系统，为 HMF 的氧化增添了新的维度和另一个有前途的工具箱。本综述讨论了使用新兴协议的贵金属、非贵金属和无金属系统催化氧化 HMF 制备 2,5-呋喃二甲酸（FDCA）和其他中间体的最新进展。不仅可以通过常见的催化剂改性，即金属的性质、制备方法和所使用的载体的性质，而且可以通过使用创新的工艺来获得 HMF 的选择性下游氧化产物。
