摘要
Single-atom catalysts(SACs)are promising in some reactions typically promoted by homogeneous catalysts.However,the leaching of active species from the support in liquid-phase reactions hinders their potential applications.Herein,taking the hydroformylation reaction as an example,we report ionic liquid(IL)-induced stabilization of single Rh atoms against leaching.Among the ILs examined.
