A novel green route to synthesize sodium benzoate from the one-pot oxidation of benzyl alcohol using air as the oxidant and AuAg/TiO2 as the catalyst under solvent-free conditions is presented. This process proceeds with advantages from the viewpoint of green chemistry due to non-toxic reagents, no waste emission and high recyclability of catalysts, which can retain high catalytic activity (yield > 75%) even after 6 runs.
