An inexpensive Fe doped aluminoborate consisted of 18％Fe in PKU-1 material that exhibits high selectiv-ity of 4-hydroxymethy-2,2-dimethyl-1,3-dioxolane(Solketal,98.3％),considerable activity(TOF 51.7 h-1),and recyclable ability in the ketalization of glycerol to Solketal with acetone at 318 K has been developed.Our study demonstrated that the structure of Fe(less agglomerated iron species vs.FeOx clusters)can be tuned by changing Fe loading in the PKU-1 material,which correlated well with experimental observa-tions.Furthermore,the surface boron sites were promoted by iron loading and behaved as Lewis-acid sites to facilitate the reaction process of glycerol ketalization,while the Solketal selectivity was closely related with the structure of iron species in PKU-1,which was proved by kinetic studies,density function theory(DFT)calculations,and a series of spectroscopy studies.This investigation demonstrates that the surface B sites can play important roles in the reaction instead of being spectators.
