Nanoceria-Templated Metal Organic Frameworks with Oxidase-Mimicking Activity Boosted by Hexavalent Chromium

The high toxicity and mobility of hexavalent chromium (Cr(VI)) allow it to easily spread and bioaccumulate, and its detection is a major part of environmental protection. In this work, an innovative method is developed for preparation of cerium oxide nanorod-templated metal–organic frameworks (CeO2NRs-MOF). The in situ growth of MOF on the surface of CeO2 nanorods (CeO2NRs) enhances its oxidase-like activity. In the presence of a trace amount of...
