▎ 摘　　要

Graphene oxide frameworks (GOFs) tailored with heteroatom-containing organic ligands were utilized for the efficient confinement of Pd nanoparticles (NPs) to achieve highly recyclable Pd catalysts for Suzuki-Miyaura cross-coupling reaction (SMC). The tailored GOFs were constructed using benzene-1,4-diboronic acid as a pillaring unit and N- and S- containing additional organic ligands to anchor Pd NPs. Highly dispersed Pd NPs with narrow size distribution were generated inside the gallery space of the GOFs. The presence of the anchoring ligands significantly enhanced the stability of Pd NPs via strong Pd-N and Pd-S bonds, leading to high activity and recyclability in the SMC reaction. [GRAPHICS]
