▎ 摘　　要

A novel nanosheet-structured material, namely graphene oxide anchored with sulfonic acid-functionalized glycerin (GO@Gl-SO3H), was prepared and characterized by FTIR, EDS, FESEM, TEM and XRD analyses. Afterward, its catalytic performance was examined for the synthesis ofN,N '-alkylidene bisamides through the reaction of benzamide (2 eq.) and arylaldehydes (1 eq.) under solvent-free conditions. GO@Gl-SO3H was a highly effective catalyst for the reaction and afforded the products in high yields and short reaction times. Graphic abstract
