Abstract

The combination of gold (Au ⁰) and tricobalt tetraoxide (CO ₃O ₄) prepared by coprecipitation gives high-performance heterogeneous catalysts for hydroformylation reaction with selectivity above 85% in desired aldehydes, although neither Au ⁰ nor CO ₃O ₄ have been demonstrated in this reaction and show poor activities. The A11/CO ₃O ₄ catalysts can be recycled by simple decantation with slight decrease in catalytic activity along with recycle times. The role of Au may mainly promote in situ reduction of CO ₃O ₄ to Co ⁰ catalyzing the hydroformylation reaction.
