Hydroformylation is a 100% atom-economical reaction using syngas and olefins to produce aldehydes, which find wide application in plasticizers, surfactants, pharmaceuticals, agrochemicals, flavorings, etc. The increasing demand of aldehydes and alcohols in the national economy, as well as the development of the petrochemical industry, boost the rapid development of olefins hydroformylation. Nowadays, hydroformylation has become one of the most important technologies using olefins to produce oxo chemicals. More than 10 million tons of oxo chemicals are produced via homogeneous hydroformylation around the world per year. Homogeneous hydroformylation catalysts show excellent catalytic activity and selectivity. But the difficulty in separation of catalysts from reaction mixtures cannot be ignored. Although heterogeneous catalysts are inferior in activity and/or selectivity, they are extremely more preeminent in separation than homogeneous catalysts. Therefore, how to combine the advantages of heterogeneous and homogeneous catalysts to realize efficient heterogeneous hydroformylation is the research hotspot currently. In the past several decades, a good deal of efforts has been devoted to developing heterogeneous catalysts for hydroformylation, including molecular catalysts, metal nanoparticles catalysts and metal single atom catalysts: (1) Heterogeneous molecular catalysts are prepared by anchoring organometallic complex on the surface/framework/pores of supports. The study focuses on keeping the activity and stability of the immobilized organometallic complex. Currently, porous organic copolymers supported Rh complex, which can steady run for 1000 h, show great potential in the industrial application. (2) The activity, selectivity, and stability of metal nanoparticles catalysts are relatively low. Both phosphorus ligands and inorganic promoters have been employed to improve the catalytic performance of metal nanoparticles catalysts. However, the unclear relationship of structure-activity limits the development of an efficient catalyst. Combining in situ characterization technique, illustrating the effect of promoters on catalytic performance of metal nanoparticles catalysts in hydroformylation will be one of the primary targets in the future. On the other hand, developing new metal nanoparticles catalysts, such as highly crystalline metal phosphides, may be a possible breakthrough in this field. (3) Although single atom catalysts show comparable activity with homogeneous catalysts, their regioselectivity and stability are still unclear. Further research should focus on the relationship of single atom catalysts with hydroformylation, and developing efficient and stable single atom catalysts.
