摘要

•Porous MgAl2O4 spinel-supported Mn3O4 catalyst was successfully synthesized from MgAl-LDH via thermal and chemical treatment, followed by Mn oxide loading.•High surface area and medium acid-base properties of the catalyst enhanced the PET conversion and BHET yield.•The catalyst was highly recyclable without significant deactivation and regenerable with complete recovery of the initial activity.
