Carbon-supported Co/Co3O4 hybrid catalyst: an efficient non-noble metal catalyst for the hydrodeoxygenation of vanillin

Abstract

Developing Co-based catalysts with high efficiency and low cost is significant for the efficient hydrodeoxygenation of biomass-derived vanillin to 2-methoxy-4-methylphenol (MMP). Herein, a unique carbon-supported Co/Co₃O₄ hybrid catalyst (Co–Co₃O₄/C-230), where both metallic Co and defective Co₃O₄ were important, was designed and fabricated for this transformation with a yield of 98.3% at 100 °C.
