A green edge-hosted zinc single-site heterogeneous catalyst for superior Fenton-like activity.

ABSTRACT: Developing green heterogeneous catalysts with excellent Fenton-like activity is critical for water remediation technologies. However, current catalysts often rely on toxic transitional metals, and their catalytic performance is far from satisfactory as alternatives of homogeneous Fenton-like catalysts. In this study, a green catalyst based on Zn single-atom was prepared in an ammonium atmosphere using ZIF-8 as a precursor. Multiple characterization analyses provided evidence that abundant intrinsic defects due to the edge sites were created, leading to the formation of a thermally stable edge-hosted Zn-N₄ single-atom catalyst (ZnN₄-Edge). Density functional theory calculations revealed that the edge sites equipped the single-atom Zn with a super catalytic performance,
