▎ 摘　　要

Graphene oxide (GO) prepared by a modified Hummers' method exhibits excellent catalytic performance in the synthesis of polyoxymethylene dimethyl ethers (PODEn) from methanol (MeOH) and trioxymethylene (TOM), owing to a synergy between the sulfonic groups and the hydroxyl and carboxyl groups present on the surface of GO with a unique layered structure.
