As shown herein, selectivity of aerobic oxidation of benzyl alcohol with gold nanoparticles dispersed on Al sub(2)O sub(3) support is solvent-controlled. Using different solvents, the reaction was directed toward a variety of products: benzaldehyde, benzoic acid or benzoic esters were selectively pr...
