Abstract:This study demonstrates the use of a MnO 2 -coated gas-permeable membrane for efficient radical delivery to water. MnO 2 of various morphologies� including nanowires (NW), nanosheets (NS) and nanoflowers (NF)�were synthesized, characterized, and evaluated according to their catalytic ozonation. In the presence of dissolved ozone, all forms of suspended MnO 2 resulted in elevated hydroxyl radical exposure but still differed across morphologies. MnO 2 NS resulted in a more efficient catalytic ozonation per mass … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
