Ionic liquids with multiple hydrogen bonds as metal-free catalysts for efficient hydrolysis of PET under relatively mild conditionsOA
Due to the strong hydrophobicity of PET,chemical catalysts usually require harsh conditions.Herein,inspired by the catalytic sites of PETase,we reported a metal-free catalyst with both high stability and activity,which could achieve almost complete hydrolysis of PET(≥99%)under relatively mild conditions(100℃,PH≈8).Mechanistic investigations showed that hydrogen bonds played an important role.With the increase of hydrogen bond multiplicity and strength,the reaction barrier decreased gradually.We believe that this work might provide a direction for the development of efficient metal-free catalysts and have great industrial application prospects.
