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.
