A convenient method for the preparation of [4-hydroxy-TEMPO + NaCl]/SiO<sub>2</sub> was developed. And [4-hydroxy-TEMPO + NaCl]/SiO<sub>2</sub> with Fe(NO<sub>3</sub>)<sub>3</sub>·9H<sub>2</sub>O was used for an aerobic oxidation of alcohols to carbonyls under mild reaction conditions. Alcohols were converted to the corresponding carbonyls in good to excellent yields. [4-Hydroxy-TEMPO + NaCl]/SiO<sub>2</sub> can be easily separated from the reaction mixture by filtration and reused at least six times.
