Аннотация: Designing efficient catalysts for hydrodeoxygenation(HDO) is vital for upgrading biomass-derived feedstocks intocleaner fuels and high-added value chemicals. In this study, weinvestigated two distinct strategies for synthesizing Ni-modifiedmolybdenum carbide (Mo2C) catalysts: a one-step microwaveassistedcarburization method (NiMo2C) and a sequentialapproach involving incipient wetness impregnation of microwavesynthesizedMo2C with nickel nitrate (Ni/Mo2C). Comprehensivephysicochemical characterization using XRD, XPS, SEM/EDS,TEM, BET, and H2-TPR revealed pronounced differences in thestructure and surface chemistry. These structural differences inmorphology, dispersion, and metal−support interactions significantlyinfluenced catalytic behavior. Ni/Mo2C demonstratedsuperior performance in guaiacol HDO, achieving an overall conversion of 98%, mostly forming high H/C products (cyclohexane),which are exclusively displayed by this catalyst. Additionally, the catalyst displays high stability, enabling the same conversion toproceed for more than 10 h. The findings underscore the critical role of synthetic pathways in tailoring the structure−functionrelationship of carbide-based catalysts for biomass conversion.
