A new efficient heterogeneous catalyst is introduced for the oxidation of ethylbenzene. The catalyst was obtained in three steps: functionalization of cellulose with d ‐penicillamine, deposition of Fe 3 O 4 nanoparticles on cellulose– d ‐penicillamine and then anchoring of Co(II) to the magnetic cellulose– d ‐penicillamine. High yield and excellent selectivity were achieved for the oxidation of ethylbenzene to acetophenone in ethanol under reflux conditions using H 2 O 2 as a green oxidant. Also, the recovered catalyst could be applied six times without a decrease in activity.
