Summary: The preparation of highly dispersed metal catalysts with strong electronic metal-support interactions (EMSIs) is of great significance. In this study, oxygen vacancies (OVs) were generated on the surfaces of Co3O4 nanorods (NRs) through NaBH4 treatment, and then the generated surface OVs were used to anchor gold clusters. The resulting catalyst showed significantly improved conversion of vanillin and selectivity to 2-methoxy-4-methylphenol (MMP), attributed to the strong EMSIs between the OV-enriched Co3O4 NRs and the gold clusters.
