Ferrate (Fe(VI), K2FeO4) has attracted much attention in water treatment for its high redox potential, especially under acidic conditions. Although interests have been arising the performance of Fe(VI) at pH below 7.0, a contradicting trend second order reaction rates (kapp) was observed conditions, and reactive species (i.e., high-valent iron or hydroxyl radicals (HO•)) oxidation remains uncle...

Methods allowing the oxidation of graphite to graphene oxide (GO) are vital important for the production of graphene from GO. This oxidation reaction has mainly relied on strong acid strategy for 174 years, which circumvents issues associated with toxicity of reagent and product, complex post-treatment, high cost and waste generation. Here, we report a green route for performing this oxidizatio...

The epitaxial structures of SrFeO(2.5) films grown on SrTiO(3) (001) and (111) substrates by PLD are reported. A layer-by-layer growth mode was achieved in the initial stage on both substrates. The films were stabilized with a monoclinic structure, where we identified the in-plane domain structures and orientation relationship. Our study presents a guide to control the heteroepitaxy of (111)-or...

Increases in harmful algal blooms has negatively impacted many surface-sourced drinking water utilities. To control these blooms, utilities implement pre-oxidation with ozone, chlorine, or permanganate; however, of algae both positive and negative quality outcomes. This study investigated ferrate (Fe(VI)) as an alternative oxidant by measuring its effect on cell lysing, surface characteristics,...
