摘要：

An adsorbent with deep-treatment ability and high selectivity for arsenic removal is strongly in need in water treatment. A new composite structure combining ultrasmall (sub-2 nm) nanoparticles (NPs) with metal–organic frameworks (MOFs) has been prepared here. In this structure, ultrasmall (sub-2 nm) hydrous ferric oxide nanoparticles (HFeO) were in-situ generated inside a Fe-based MOF (MIL-100) through a room-temperature reduction process. The structure, denoted as HFeO@MIL-100, demonstrates extraordinary adsorption ability for As (V), with a...
