采用浸渍法制备了铬锰（Cr-Mn）双金属催化剂并用于5-羟甲基糠醛（HMF）催化氧化制备2，5-呋喃二甲酸（FDCA）。研究了不同铬掺杂比例对催化效果的影响，并探索了HMF催化氧化制备FDCA的最佳反应条件。结果表明，在最佳反应条件下HMF转化率为99%，FDCA产率达到87.9%；Cr-Mn双金属催化剂表现出优异的催化性能，同时具有良好的稳定性，循环4次后仍保持较高的活性。该非贵金属催化剂为催化HMF制备FDCA提供了一种廉价、简便的制备方法。

A chromium-manganese bimetallic catalyst is prepared via impregnation method for the catalytic oxidation of 5-hydroxymethylfurfural (HMF) to prepare 2, 5-furandicarboxylic acid (FDCA).The influence of different chromium doping ratios on catalytic performance is studied, and the optimal reaction conditions for HMF to FDCA are explored.It is indicated that under the optimal reaction conditions, the conversion rate of HMF reaches 99%, and the yield of FDCA reaches 87.9%.This Cr-Mn bimetallic catalyst exhibits excellent catalytic performance and good stability, maintaining high activity after 4 cycles of service.This method provides an inexpensive and convenient catalyst preparation method for catalyzing HMF to FDCA over non precious metal catalyst.
