Synergistic Catalytic Conversion of Cellulose into Glycolic Acid over Mn-Doped Bismuth Oxyiodide Catalyst Combined with H-ZSM-5

An eco-benign catalytic system in which Mn-doped bismuth oxyiodide (BiOI) was combined with H-ZSM-5 as a catalyst for direct hydrolysis and oxidation of cellulose into glycolic acid at 180 degrees C in an O-2 atmosphere achieved excellent catalytic performance with a yield of 82.6%. The prominent catalytic performance was largely attributed to the synergistic effect between Mn species with BiOI and the stronger Bronsted acid sites over HZSM-5. Furthermore, the as-synthesized catalyst displayed extraordinary catalytic performance after five successive reaction runs. Most importantly, this study provides an eco-friendly strategy to design efficient heterogeneous catalysts for converting biomass resources into biofuels and high-value-added chemicals.
