Abstract Selective and efficient production of vanillin from lignin‐derived feedstocks has attracted attention to replace its current manufacturing process. Transition metal‐based catalysts supported on mesoporous aluminosilicate were synthesized using a mechanochemical approach and subsequently investigated in vanillin production via the selective oxidation of isougenol. The mechanochemically synthesized catalysts exhibited a high isoeugenol conversion under mild conditions using H 2 O 2 as oxidizing agent. Nb‐based catalysts were found to provide the optimum conversion/selectivity under the investigated conditions (69% conversion, 66% vanillin selectivity, 2 h reaction). The synergistic effect between Fe/Nb and Al accounts as important key factor for optimum activity of catalytic systems.
