Our catalyst could be reused three times without appreciable loss in activity. The catalytic activity of the Co3O4 nanoparticles was found to be similar to its homogenous precursor (cobalt acetate) and greater than the commercial Co3O4 oxide. The detailed characterization results of morphology, size and structure of the prepared Co3O4 nanoparticles obtained by XRD, FT-IR, H-2-TPR, HR-TEM and cyclic voltammetry technique were used to understand the roles of various Co species in directing the selectivity towards vanillin.</p>1 aJha, Ajay1 aRode, Chandrashekhar, V.  uhttps://library.ncl.res.in/content/highly-selective-liquid-phase-aerobic-oxidation-vanillyl-alcohol-vanillin-cobalt-oxide-0
